The manufacturer wants to get more market share of  green laser pointer .
Laser cutting: laser cutting technology is widely used in the processing of metallic and nonmetallic materials, can significantly reduce processing time and reduce processing costs, improve the quality of the workpiece. Pulsed laser for metal materials, continuous laser for non-metallic materials, which is an important application field of laser cutting technology. Laser application in the industrial field limitations and shortcomings, such as using a laser to cut the food and plywood are not successful, the food is cut also was burning, cutting plywood in the economy is still far from substandard operator . Laser welding: laser beam in the material, it will be heated to melting, so that the components are joined together with docking, that is welded. The appearance, parameters or performances of  green laser pointer  can be made specially.
Laser welding than the smaller power of the laser beam cutting metal, the material to melt without it gasification become a continuous solid structure after cooling. The laser welding technology has dissolved pool purification effect, would be pure weld metal, apply to the similarities and differences between the metal material welding. Due to the high laser energy density, melting point, high reflectivity, high thermal conductivity and physical properties vary a great deal of metal welding is particularly beneficial. Using laser welding does not require any solder, so to exclude the possible contamination of welded components. 
If the microscopic particles such as atoms or molecules with energy level E2 and low energy levels E1, E2 and E1 level population number density of N2 and N1, the existence of spontaneous emission between the two-level transition, the stimulated emission transition and stimulated absorption transition of the three processes. By stimulated emission transitions generated by stimulated emission of light, with the same frequency, phase, direction of propagation and polarization direction with the incident. Therefore, a large number of particles at the same excitation of the coherent radiation field generated by stimulated emission of light is coherent. Monochromatic energy density by the stimulated emission transition probability and the stimulated absorption transition probabilities are proportional to the incident radiation field. 
So far, the clinical use of laser medical equipment have been dozens of varieties, including a variety of wavelengths from UV to visible light and infrared, and contains a variety of output modes of the continuous, pulse, giant pulse, ultra pulse. Laser therapy equipment in the clinical application point of view can be divided into the following broad categories: ophthalmic laser treatment devices, surgery, laser surgery equipment Dermatology laser treatment devices used for cosmetic purposes, photodynamic therapy laser therapy equipment, dental laser equipment and laser physiotherapy equipment and so on. Laser technology in military applications of laser weapons has its uniqueness, it is widely used in air defense, anti-tank, the bomber self-defense and military purposes. The laser is able to become powerful weapons. The green green laser pointer will emit the green laser beam light. Only after the commission process of the power of  green laser pointer is well controlled.Actually, the life time of green laser pointer is the life time of the laser module
