Against Iran announced made "significant progress" message, and the United States and Israel have came forward to say that Iran is bluffing, there is no need to give too much attention on nuclear research. As a result, it is not easy to make sense to expand the capacity of a green laser pointer.
In addition, in order to further "shock and awe" Iran, the United States announced on the 16th to impose sanctions on Iran's Intelligence and Security (MOIS. The United States to refer Iran's bluff 15 days, Iranian President Mahmoud Ahmadinejad announced on national television that Tehran nuclear reactor mounted to the first domestic 20% enrichment of nuclear fuel rods used in centrifuges to enrich uranium has increased by 3,000, and ordered to build four nuclear reactors. Iran recently announced a "major achievement", Distinctions also exist in the infrared and radio frequency technology in the production of green laser pointer.

According to the theory of the solid phase transformation and chemical bonds in the coating to add some element of cable, ceramics and substrates to produce the chemical reaction to form covalently bound to improve the interface strength at the interface. , Depending on the alloy modes of supply, laser cladding can be divided into two types: synchronization alloy and alloy front method. Substrate cladding surface preparation. In order to remove dirt and corrosion of the substrate cladding parts. Preheat and post heat treatment. Its role is to prevent the martensitic transformation of the heat affected zone of the substrate resulting in the cracks of cladding layer, therefore, appropriate to reduce the temperature difference between the substrate and cladding layer to reduce the cladding layers expand and contract to produce the stress increase melting layer of liquid retention time can be beneficial to exclude air bubbles within the melt layer and slag material. The single projection green laser pointer will be shown.
The actual production process are often used in warm-up method to eliminate or reduce the crack of the cladding layer, especially for easy-to-cracking of the substrate must be preheated in the cladding layer cracking tendency is smaller, and sometimes also used to preheat reduce the melting overburden stress and improve the cladding quality. Preheated flame gun heating, induction heating and stove heating, the first two heating preheating the substrate surface within a certain range, and can be carried out simultaneously preheating and laser cladding.

The surface treatment of green laser pointer plays a decisive role inthe manufacture
The high output power of a lens focusing the laser, the resulting energy density of sunlight hundreds of times. Laser welding using a laser beam of excellent directivity and high power Mody density characteristics of the work. The laser beam is focused through the optical system in a small area, welded at the formation of an energy highly concentrated heat source area within a very short time, so that the solder material melts and forms a solid solder joint and the weld. Commonly used in laser welding of two kinds: the pulsed laser welding and continuous laser welding. The former is mainly used for single-point fixed continuous and thin material welding. The latter is mainly used for welding and cutting large pieces of thick. The surface treatment of green laser pointer plays a decisive role in the manufacture.
Laser welding characteristics of the processing methods. Non-contact processing, without pressure on the workpiece and the surface treatment. Solder joints, high energy density, suitable for high speed machining. Welding a short period of time, both on the outside and the heat-affected, but also the thermal deformation and heat affected zone is small, and is particularly suitable for processing high melting point, high hardness, specialty materials. Do not need to fill the metal, does not require a vacuum environment (in the air), not like the electron beam in the air as the danger of X-ray. Compared with exposure to welding process. Electrodes, tools and other wear and tear. Processing noise pollution to the environment. Small parts can be processed. In addition, the welding can also be carried out through the transparent material of the wall. The manager and the customer are negotiating the price ofgreen laser pointer.
When the low power density and longer exposure time while welding pieces of thin, usually mainly to the melting heat transfer mechanism. On the contrary, is based on deep penetration of the melting mechanism to main. Process characteristics and its influencing factors. The laser input energy density. The method of adjusting the laser energy density: the adjustment of the laser output energy (adjust the excitation voltage). Adjust the spot size (to regulate the exit focal length). Change the energy distribution in the spot (to change the fiber type: the peak-shaped output type - the GI optical fiber, the trapezoidal output type-SI type fiber). The worker should pay attention to self protection during manufacture process ofgreen laser pointer.
Change the width of the radio pulse and waveform. Most metals in the laser exposure, the majority of laser energy reflected from the welding process begins the moment a corresponding increase in beam power. Using pulsed laser seam defended by two arts, you can access arc plate to ensure the quality and consistency of the entire welding segment. When the melt or vaporize the metal surface, the reflection rate is decreased rapidly. The main factors affect the material of the laser beam absorption. Laser absorption rate of the metal materials at room temperature below 20 ℃; when the metal temperature reaches the branded point melting and gasification, the absorption rate increased to 40 ~ 50%. The innovative design of green laser led greatly improve the quality ofgreen laser pointer.

Customer in the design liaison meeting ofgreen laser pointer
Enough to be a missile charred up to tens of kilowatts of laser energy to produce, require thousands of liters of toxic chemicals - ethylene, nitrogen-based and three fluoride laser weapons is not only abnormal heavy, worse , fired several times not to have to re-filling a number of chemical substances. A huge number of toxic chemicals placed in the aircraft or delivered to the battlefield would like to decree generals were prohibitive. In addition, heavy rain or fog in the penetration of the laser will be greatly reduced. Last year, the U.S. canceled their tactical high-energy weapons program, many people think that the next one will soon turn serious budgetary overruns 747 laser weapons launch platform. However, the charm of the laser weapon is hard to resist, especially after long distance still has the advantage of high accuracy to the United States military, its hard to break away. They will try their best to solve the problem put forward by the customer in the design liaison meeting of green laser pointer.
"There is no sound, no smoke, quietly the enemy will be able to knock down, but also a long shot without filling," the U.S. Marine Corps Major General Bradley, Lott, said, "If the laser weapons can be made with the performance of , that would be coveted by the Marines. "chemical lasers can not meet the requirements, how to get the laser with practical value? We can follow the two steps. First of all, the Pentagon realized that, if you want a practical laser weapons, it can not be too hasty, you must first reduce the target. For example, do not begin with the requirements of laser weapons capable of destroying ballistic missiles, and rockets such a relatively easy target start. The worker should pay more attention to technical details ofgreen laser pointerduring manufacture.
But the scattering of light bulb, these photons have a very good direction, the photon is reflected back and the route of the two excitation photons are identical. In addition, unlike almost all wavelengths of visible light from the spectrum synthesis of ordinary light, the wavelength of the laser is a single (specific wavelength depends on the laser gain medium, the atom type). As long as the laser radiation of sufficient energy to the object, the surface will have a high temperature until combustion. The first laser test is carried out by the 1960s, was used in the gain medium is a ruby crystal. The supply manager ofgreen laser pointerwill arrive.
But only a few hundred watts of power this early solid-state lasers produce laser - This laser eye surgery is actually right. To destroy a missile, laser power must be thousands of kilowatts, researchers gave up early in the solid-state lasers, turn to the reason of the heavy chemical laser, can wait for the final they still failed. However, there is another kind of laser methods, the use of lasers of this method does not require large amounts of toxic chemicals, no crystals, do not even need the gain medium, which is the free electron laser (FEL). Such lasers ultra-high-energy electron beam to stimulate the reaction. Technology perfection of green laser led is necessary.

From the table shows that the plasma cloud size and the protective gas changes, the minimum helium, nitrogen, followed by argon. Plasma sizes, and the penetration depth is more shallow. The reason for this difference is first of all because of the different degree of ionization of the gas molecules, the other protective gas density caused by the metal vapor diffusion difference. Helium ionization minimum, the minimum density, it can quickly get rid of the metal vapor rising from the metal bath. With helium as the shielding gas, the maximum degree of inhibition of plasma, thereby increasing the penetration depth and welding speed; light can escape, it is difficult to cause stomata. Of course, from the effects of actual welding, argon protective effect is pretty good. The former technology of green laser pointer with remote control is slower.
The plasma cloud penetration effects are most obvious at low welding speed zone. When the welding speed increases, its impact will be reduced. The shielding gas to reach the surface through the nozzle exit pressure injection, hydrodynamic shape and diameter of the exports of the nozzle size is very important. It must be large enough to drive the spray of the protective gas covered surface, but in order to effectively protect the lens to prevent the metal vapor contamination or metal splash damage to the lens, nozzle size should be limited. The flow must also be controlled, otherwise laminar flow becomes turbulent protective gas atmosphere involved in the bath, and ultimately the formation of pores. In order to improve the protective effect, but also with additional lateral blowing. Various functions of laser pointer with remote control will be introduced.
Shielding gas through a smaller diameter of the nozzle at an angle directly into the hole deep penetration welding. The shielding gas is not only inhibited the surface of the plasma cloud, and to exert influence on the formation of the hole plasma and holes, deep penetration further increase, deep wide comparison of the ideal weld. However, this method requires precise control of gas flow size, direction, otherwise easily lead to turbulence and destruction of the molten pool, leading to the welding process is not stable. Lens focal length. Welding usually focus the convergence of the laser is generally used in the 63 ~ 254mm (2.5 "~ 10") focal length lens. The focused spot size and focal length is proportional to, the shorter the focal length, the smaller the spot. Users will completely free from staying at the side of the computers by using green laser with remote control.
Focal length length also affects the depth of focus, depth of focus with the focal length increased simultaneously, so a short focal length can increase the power density, but the depth of focus small, must be accurate to maintain the spacing of the lens and the workpiece, and the penetration depth is not large. Spatter and laser mode by the welding process, the actual welding using the shortest focal deep multi-focal length of 126mm (5 ") when larger joints or by increasing the spot size to increase the weld can be Select 254mm (10 ") focal length lens, in this case, in order to achieve the deep penetration in pinhole effect, require a higher laser output power (power density). When the laser power exceeding 2kW, especially 10.6μm CO2 laser beam, due to the use of special optical materials constitute the optical system. green laser led with remote control is helpful to speeches.
In order to avoid focusing lens has been the risk of optical damage, often selected reflection focusing method, commonly used for mirror polished bronze mirrors. Due to effective cooling, it is often recommended for high-power laser beam is focused. Focus position. Welding, in order to maintain sufficient power density, the focus position is essential. The focus of the relative position of the surface changes directly affect the weld width and depth. Figure 2-6 shows the focus position on the 1018 steel penetration and slit width effects. In most laser welding applications, usually the location of the focus is set below the surface about the required penetration depth 1/4. The location of the laser beam. Different materials, laser welding, laser beam position control the final quality of the weld. The used can simply press the related buttons on green laser pointer .

The infrared defect of green laser pointer could be overcome by the2.4GHz technology
Principle of laser destroyed the target has two aspects: First, perforation, and second floor split. The so-called hole is a high power density laser beam to the target surface rapidly melting, vaporization and then evaporated, vaporized material out spray, recoil shock wave formation in the target and through a hole. The so-called spallation, laser energy is absorbed by the target surface, the atoms are ionized, in vitro formation of "cloud." "Cloud" outward expansion of the jet to the depths of the formation of stress wave propagation. Once the connection is successful, the indicator light of green pointer led stops flickering.Stress wave reflection caused by target pulled off to form a "spall" damage. In addition, the plasma "cloud" but also ultraviolet radiation or X-rays, destroy target structure and electronic components. The small size of the role of laser weapons, but the key parts of the damage on the target, the target can cause devastating damage.
First, the laser marking 1, laser marking principle: laser marking laser beam is used in a variety of different surface materials marked with permanent marker. Marking effect of evaporation of surface material is exposed through deep material or surface by light leading to the chemical and physical changes, "carved out" signs, or light burned through part of the material, showing the required etching patterns, the text. The battery electric quantity indication is used for indicating the service condition of green laser .Currently, the accepted principles are two: "thermal processing" has a high energy density laser beam (which is the focus of the energy flow), irradiation in the surface to be machined on the surface absorb the laser energy, heat generated in the irradiated area excitation process, so that the material surface (or coating) temperature rise, resulting in abnormal, melting, ablation, evaporation and other phenomena. "Cold" load high energy (UV) photons, can interrupt the material (especially organic material) or the chemical bonds within the surrounding medium, to the occurrence of non-thermal process the material damage. This cold processing laser tag has a special significance, because it is not thermal ablation, but do not have a "thermal damage" side effects, break chemical bonds of the cold strip, and thus be processed in the surface layer and in the vicinity do not produce heat or thermal deformation and so on.The battery electric quantity indication helps to judge if it needs to change the battery of green laser pointer . For example, the electronics industry in the use of excimer laser deposition of chemicals on the substrate film on the semiconductor substrate out of the narrow slot. 2, laser marking features: at any regular or irregular surface marking, and marking the workpiece does not produce stress; in metals, plastics, ceramics, glass, paper, leather or different kinds of materials of different hardness print; 1) non-contact processing 2) materials are suitable for a wide range of 3) other equipment and production line integration, improve the automation of production lines; 4), marking a clear, durable, beautiful, and effective anti-counterfeiting; 5) The long service life , non-polluting; marking speed and mark a shape, energy consumption, and thus low operating cost. 6) Although the low running costs of equipment, laser marking machine marking equipment than the traditional large investment, but in terms of running costs, with much lower laser marking confidential. ① plastic transistor marking: marking machine working speed of 10 / s, if the equipment depreciation, a 5-year period, marking a cost of 0.00048 yuan / month.The laser pointer has a timer.
If you use a printing machine, its comprehensive operating cost is about 0.002 yuan / month, or even higher.
② bearing surface marking: If the bearing trisection typing, a total of 18 4, word, using galvanometer marking machine, krypton lamp to lamp life of 700 hours per, each bearing the cost of marking integrated of 0.00915 yuan.

Green laser pointer outputs green ray with power of 80mw-100mw
Successful practices such as: a profiling milling most cutting the amount of complete (heavy cutting) left in the 2-3mm allowance, the remaining amount of cutting done quickly in a high-speed machine tools, to do so has many advantages: weight cutting machine tools, processing fees low. Processing volume, accuracy is not easily reach. Tool cheap. Transferred to high-speed cutting, forming, because the processing object is close to the first knife cutting is very uniform. Forming fast and accurate. Free too polished, with the precise size. Although the tool is expensive, but time is short, cutting the amount of good performance and low cost rate. A lot of nuances. Therefore, the manufacturer will focus on the continuous wave output of green laser pointer during the production of the laser pointer.
Such as small angle conductance, detailed processing in one step instead of spark to help fast and excellent surface finish (mirror effect). It seems that the coordination of equipment this is the way to win, because it is the remaining amount of 2-3 mm in the work of stage XY two calibration G54 tailgate to complete the workpiece clamping, and for cutting small amount of the workpiece directly in high-speed machine tools. Another issue to be discussed is the issue of the spindle. Because they require low speed twisting, so be sure to spindle gearbox reduction ratio to improve the speed of the torque accuracy is inevitable, so is unlikely to use a small radius tool for CNC milling and machining centers. The continuous wave output of laser pointer should be taken good care during production.
For engraving and milling machine, spindle work around 20,000-30,000 RPM before work, turning precision generally 2 μ, or the cutting knife phenomenon all very serious, so be sure to electric spindle motor and spindle are one. For high-speed cutting equipment is concerned, the requirements of the Built-in electric spindle with torque have oil and water coolers to maintain spindle temperature constant, but also in the low speed spindle power to more than 7.5-8KW, speed over 25000RPM . New developments in laser treatment of children with skin hemangioma. Laser Medicine is one of today's rapidly developing field of medicine, there has been a variety of laser treatment of vascular tumor, its effect is significant, side effects, has become a commonly used method for the treatment of some children's skin hemangioma. The performance of the continuous wave output of green laser is good enough.
Laser and light are very different from, it is the substance by stimulated emission of radiation luminescence and the bundle of light. The high brightness of laser energy density, is the brightest source in the world today. Strong laser brightness up to sunlight brightness of 10 million billion times. When this light energy into heat energy, you can instantly produce a few thousand to tens of thousands of degrees of heat. The laser is a bundle of approximately parallel light, and it fired only in one direction, a very small divergence angle, long range, can form a very small point of light focused by a lens. Laser high brightness, monochromatic, directional and coherent laser energy in time and space, the spectrum is highly concentrated. So that the good and continuous use and operation of green laser led can be ensured.
These characteristics of the laser allows the laser beam to high energy can be focused to a small spot, ideal for precision cutting and gasification operations. Intense laser irradiation of biological tissue, can instantly generate hundreds or even thousands of high temperature, protein denaturation and coagulation of the thermal effects of the biological organization, even to the carbonization or gasification [1]. Can be divided into two parts by mechanical action produced by the laser irradiation, the pressure generated by laser radiation pressure on biological tissue, ie, pressure, known as time pressure, because the laser energy density, which will have a huge radiation pressure, laser generate pressure up to 104 ~ 105 Pa; caused by thermal expansion and phase transitions, as well as ultrasound, shock wave, electrostriction and other biological tissue absorption of strong laser-induced pressure, called secondary pressure. green laser pointer has attracted many customers in the domestic and oversea market.

The economical technology of green laser pointer will improve the costperformance
Therefore, to calculate in advance the amount of damage the target without instantaneous. High-energy laser weapons rely mainly on infrared detectors to capture, track goals, operational process from electromagnetic interference, the defender is difficult to electromagnetic interference means to reduce the probability of hitting the target. High-energy laser weapons firing recoilless force, transfer of fire, fire can be adjusted in the range of 360 °, after hitting a target, simply adjust the angle to attack another target, which can damage the air targets in a short time a large number. Difficult to see that high-energy laser weapons into combat, it will lead to damage the air targets of revolutionary change, people will have to face this harsh reality. The economical technology of green laser pointer will improve the cost performance.
Find out the high-energy laser weapons, the damage mechanism of air targets is very important for the defense laser weapons. The destructive effect of high-energy laser weapons have the destructive effect of thermal ablation, shock damage effects and radiation damage effects. This paper will damage mechanism of the destructive effect of these three preliminary analysis, and to explore appropriate means or measures of defense. Laser to the target, the target material substances in electronic collision due to absorption of light energy converted to heat, rapid increase in temperature of the material surface to reach a certain temperature the material is melting or gasification, resulting steam at very high speed expands outward and splashes it, washed away the molten material droplets or solid particles, thereby causing the material on the pits and even perforation, this effect is called thermal ablation damage effects. The destructive effect of thermal ablation is the most important laser weapon damage. green laser pointer is very important in business contact and so on.
However, high power pulsed laser and material effect, the shielding effect of the surface plasma on the laser ablation effect and negative affect. Laser damage threshold of the thermal ablation of the material can be described with the energy density threshold, the available power density threshold description. In the case of rectangular short pulse laser energy density threshold for a given material damage is a constant power density threshold and pulse width is inversely proportional; in the case of long rectangle pulse, the laser damage to the material given energy density threshold value and the pulse width is proportional to the square root of power density threshold and pulse width is inversely proportional to the square root. Users want to highlight some key points with help of green laser pointer.
In other words, short laser pulses mainly rely on to achieve the power density threshold the material ablation destruction, long-pulse laser energy density threshold depends mainly on the reach ablative destruction of the material. Different material and material of the laser absorption and reflection of the same physical concepts that reflect this ability is the absorption coefficient and reflection coefficient of the material on the laser. According to the law of conservation of energy, the laser can not penetrate the material reflection coefficient and the absorption coefficient of 100%. Undermine the ability of laser ablation on thermal, laser and the material is inversely proportional to the reflection coefficient, the absorption coefficient is proportional to the laser and the material. The laser ray color of green laser led can be chosen by the customer according to the need.
The same melting point of the two materials, when the laser power is small, the thermal conductivity coefficient of the material Shaorong time was needed, smaller thermal conductivity of the material Shaorong takes less time; with the incident laser power time gradually increased, the materials under the action of the laser thermal conductivity, a gradual reduction of the two materials is Shaorong required to gradually close; when the radiation laser power is large enough, the material is too late in the laser induced heat conduction, two The material is Shaorong time required to reach consensus.

What is the greatest benefit of green laser pointer
What is the greatest benefit of green laser pointer ? the very high frequency of the laser cutting, less power, like 250W following a short period of time the stall will not burn the motor. Auto glass mobile coders with the CNC machine tools, the formation of an antique furniture trends. Architectural models: large, low-power computer laser pointer. It is necessary to understand the laser pointer the most appropriate range of applications: badges: low-power laser pointer (engraving machine), high power or low-power computer laser pointer. What has caused the cutting dislocation.
Relevant function buttons on a portable green laser pointer can be used to control electronic presentation. The workpiece is cut through a small hole machining spindle is usually divided into two categories: precision machining spindle, and power cut off the spindle. The stepper motor at low speeds prone to low frequency vibration phenomena # can be detected in the mechanical resonance point. For constant power output above the rated speed. And modern digital control technology is intrinsically linked to mechanical resonance point can be detected, the stepper motor at low speeds prone to the phenomenon of low frequency vibration, but in some less demanding situations often use stepper motors to do the implementation of the motor.
the stepper motor is a discrete movement of the device, but there is a big performance and applications differences. AC servo drive system for the closed-loop control can output rated torque. Although both are similar in the control mode (pulse string and direction signal) can be used to control applications. Simply by touching the keys of a portable green laser pointer , users can wirelessly flip files in a computer. that require fast start and stop, and at high speed would drop dramatically better than the stepper motor, AC servo system in a number of performance. This phenomenon of low-frequency vibration is determined by a stepper motor works very detrimental to the normal operation of the machine.
Through specific experiments show that the sculpture should be a smooth transition. Nozzles. From stop to rotation have a lower starting frequency. To ceramics, polymers, two in the engraving, so as not to run other programs, accounting for CPU time, laser cutting machine to focus on tracking system is generally composed of Focus on the cutting head and track sensor system to be used, such as the front windshield framework, the inner door panel, underbody, in the column such as the production. The targeted pages of an electronic document can be projected on the screen with a portable green laser pointer .
