Laser technology as a core of industrial manufacturing driving force, itself is constantly moving forward. To sum up, the high power laser
is toward the "faster, higher, better, shorter" in the four directions.
Laser power is getting higher and higher, the average power has more than 10 million watts. In 2013, the first commercial 100,000-watt fiber laser was installed at the NADEX Center in Nagoya, Japan for the welding of 300mm thick steel plates. Laser cutting applications are also toward a higher power development, laser cutting machine power continues to rise, has reached 8 ~ 12kW.
The beam quality of the laser output is getting better and better, and the beam quality of the fiber laser has reached a single mode of 100,000 watts. In the past year, fiber lasers, disc lasers, direct semiconductor lasers have a significant increase in brightness.
The output wavelength of the blue laser pointer
covers a shorter band, and the short wavelength laser has been widely used. Many advanced manufacturing processes require cold processing, such as in the manufacture of smart phones, often need to use short wavelength, short pulse UV laser to deal with. Short wavelength lasers have been widely used in surface marking, semiconductor wafer processing, drilling, cutting and other fields.
The pulse speed of the laser is getting faster and faster, and the ultrafast laser has been developed rapidly. It has been driven into industrial applications by means of simpler structure, more convenient operation, lower cost and more stable performance.
With the enhancement of environmental awareness, a variety of environmental cleaning technology came into being, laser cleaning technology is one of them. Laser cleaning using high-energy red laser pointer beam and the workpiece surface to remove the material interaction, the occurrence of instantaneous evaporation or stripping, without a variety of chemical cleaning agents, green pollution. Can be used to remove paint, oil, oxide, cleaning screw, rust, cleaning weld. Laser cleaning in the microelectronics, construction, nuclear power plants, automobile manufacturing, medical care, cultural relics protection, steel rust and mold decontamination, automobile manufacturing, construction and other fields have a huge market space.
Metal 3D printing is also made of the material, usually using a selective laser cladding (SLM) technology, the use of laser energy to melt the layers of metal powder, and finally made the desired shape. In 2016, SLM system sales of more than 1000, which uses the laser source is mainly fiber laser, disc laser / CO2 laser and femtosecond fiber laser, power range of 30W to 1kW or more. 3D printing of the fine degree is also getting higher and higher, print out the fine structure of the resolution has reached the order of microns.
The next five years, the market will grow steadily, and the main driver of market growth comes from unmanned aerial vehicles, autopilot vehicles, robots, military and security. Part of the green laser pointers
lighting market is car laser lighting, mainly car headlights. BMW, Audi and other well-known car manufacturers have adopted a laser lighting system. Another part of the market is safe laser lighting, such as the night environment for people riding a warning sign.
