laser pointer is design to be the focusable water proof structure.
Tube equipped with a water-cooled laser steering mirrors, red tube shielding gas. The laser generator and laser welding head is installed in "C" type rack, so the transmission optical path is short as shown in Figure 2-5. A weld light in the welds on the following round, the operation of hydraulic cylinders. High-frequency induction heaters (for strip preheating and annealing): high-frequency converter; heater (by the induction coil, transformer, oscillation circuit, capacitors and water cooler). Punching device punching in the weld at the edge, in order to achieve the detection and tracking of the weld in the follow-up process. The cutting head output device arranged in the blade box can automatically output cut head. Chute with cutting head will cut the first guide cut headband transport aircraft. Power and reliability of this structure is greatly improved. RF CO2 laser pulse controller, the switch of the power pulse current. The main role is to make the power of the modulated signal output function, such lasers can work continuously while pulse output. Its design requirements is continuously adjustable frequency and pulse width. In fact it is a square wave pulse signal generator may be of different functions of the integrated circuit, such as function generator ICL8038 single op amp LM318, the time base circuit NE555 and switching power supply controller XR3524.  Performance comparison of various incentives in Table 1. The best performance with existing technology, RF-excited high frequency excitation, followed by microwave excited is a useful technology hope I looked, DC excitation will gradually be eliminated. In the future, the direction of development of high-frequency excitation technique is to increase the power output and reduce the volume. RF excitation of the main goal is to reduce power prices, and control of radioactive contamination, and vigorously develop the diffusion cooling waveguide laser technology. After the soil of the tireless efforts of laser research, I believe the near future, high-performance, low-price, safety and environmental protection of the microwave excited. From the temperature-stable, single-mode diode lasers emitting laser to a diameter direction of the transmitter relative to the receiver. Diode laser at room temperature near.
