a.LD pumped solid-state laser

On semiconductor laser (LD) pump solid state laser devices, the development of very active in the world. In Japan, as a "photon project" national project has developed a 10 kw of small (Rod-and Slab-type) device. In the U.S., as a "precision laser processing," national projects. Research and development out of the 3 kW LD pumped solid laser device available Slab 20-30 mm large penetration welds. As the weld width is extremely small, laser beam for lateral movement can expand the width of the melt. Germany is now the development of LD pumped solid state laser disc's most high-profile thin it is small, good quality, efficient and high-power and other characteristics can be Hass has developed a LD-pumped disk laser equipment 4 kW and will develop 10 kW-class equipment. Laser Plastic welding wire.

b. semiconductor laser device
Currently, many companies are developing high-power semiconductors, has been there 2 ~ 6 kW-class commercial small devices. Due to small size, light weight, semiconductor lasers can be directly carried out on board the robot, welding and other processing, other semiconductor laser optical fiber transmission can also be used for welding. Despite the high efficiency semiconductor lasers, laser wave length but because of divergence angle, working distance (focal depth) of the shortcomings of currently available only for short laser soldering and plastic welding.

c. Laser Remote Welding (Remote Welding) equipment

Due to the high beam quality slab CO2 lasers have been brought forth, such as lasers, fiber lasers and YAG laser disc (Disc Laser) allows remote welding or laser welding, said laser scanning (Laser Scanning Welding) is possible and greatly improve the car body parts laser welding speed. At present, fixed-gantry machine + CO2 lasers, robotics + fiber laser or YAG laser disc and other auto body parts manufacturing using laser remote welding rods excited.
