As a important tool, industry laser is continuously evolution in four angles:
Higher power: laser source average output power is getting higher, the first commercial 100,000 watt laser deployed in Nagoya for welding 300mm thickness stainless steel in year 2013, in laser cutting sector, 12,000 watt lasers are gradually configured in laser cutting machines.
Better beam quality: laser source output beam quality is getting better, the beam quality already achieved 100,000 watt in single mode fiber laser, there are significant improvement in fiber laser source, disc laser source and diode laser source.
Shorter Wavelength: short wavelength laser source widely used in industry, many advanced manufacturing processes require cold processing, for example, short wavelength and short pulse laser applications in smart phone manufacturing. Short wavelength lasers already widely used in laser marking, semiconductor scribing, drilling and cutting.
Smaller pulse width: Ultrafast laser source developing fast, smaller pulse width lasers already start commercial use in industry.
According to market analysis, the following industry applications will be booming in the next few years:
Laser cleaning using high-energy laser beam to interaction with the material on workpiece surface, instantly evaporate or peel the material, no need chemical cleaning detergent, no pollution at all, laser cleaning can be used to remove paint, oil, oxide, cleaning screw, rust and clean weld.
Laser cleaning can be used in the microelectronics, construction, nuclear power plants, automobile manufacturing, medical care, cultural relics protection, steel rust removal and mold decontamination, construction and other industry sectors.
Metal 3D printing:
Metal 3D printing is a type of laser additive process, normally selective laser cladding (SLM) technique is used to melt the metal powder layer by layer and ultimately made the desired shape.
In year 2016, there were over 1,000 sets SLM systems deployed, the laser sources used in the systems are mainly fiber laser, disc laser, CO2 laser and femtosecond fiber laser, output power ranging from 30 watt to over 1,000 watt, the 3D printing resolution has reached as small as microns level.
The laser radar market will grow steadily in next 5 years, the market growth comes mainly from unmanned aerial vehicles, autopilot vehicles, robots, military and security sector.
Laser illumination market mainly from 2 parts, one part is car laser illumination, mainly car headlamp, another part is safety laser illumination, for example, warning sign for night ride.
