Laser application field
Laser machining technology is a technology that uses the characteristics of the interaction between laser beam and substance, and takes cutting, welding, surface treatment, drilling, micromachining materials and identifying objects as light sources. The most traditional application field is laser processing technology.
Laser technology is a comprehensive technology involving optics, mechanics, electricity, materials, detection and other disciplines. Traditionally, its research scope can be divided into
Laser processing system. Comprise a laser, a light guide system, a processing machine tool, a control system and a detection system.
2. Laser processing technology. Including cutting, welding, surface treatment, drilling, marking, marking, micro-carving and other processing technologies.

Development prospect of laser
Laser power is not enough to describe cutting ability, brightness is. Brightness is defined as "laser power per unit area and unit solid angle".
Comparing CO2 laser, disk laser and fiber laser, we can draw the conclusion that the brightness of fiber laser is up to 5 kW, and the fastest and thickest cutting metal plate is fiber laser.
In fact, however, cutting thick plates is not as good as CO2 laser. Although the absorption rate of carbon steel to near-infrared Yb-doped fiber laser is several times higher than that of mid-infrared CO2 laser, the slit of CO2 laser with the wavelength of fiber laser 10 is much wider than that of fiber laser (generally 2mm), and oxygen can be easily blown in.
This is why CO2 lasers have dominated solid-state lasers for 46 years. First, the increase of mass production and independent research and development of domestic laser cutting machines and the localized production of foreign first-line companies in China have narrowed the product gap and price gap between them. Users' recognition of domestic machines is getting higher and higher, and the share of 20 10 in the domestic market is as high as 80%.
Secondly, in 20 10, the sales of high-power CO2 laser cutting machines with kilowatts and above in China reached 1000, accounting for 20%-25% of the global market. Shanghai Unity Prima, Dazu Laser, Wuhan Fareilai, Pentium Chutian and other first-line manufacturers have all increased significantly. At most one company accounts for 30% of the domestic market.
