Laser is an important component of laser marking machines (laser engraving machines), welding machines, and laser cutting machines. Laser is a core component and generally accounts for 40% of the cost of a device, while high-end ultraviolet laser engraving machines account for more than 60% of the cost. Laser is mainly divided into fiber laser, ultraviolet laser, green laser, and CO2 laser. According to the different wavelengths of the laser, it can be divided into: deep ultraviolet laser (266 nm), green laser (532nm), lamp pumped YAG laser (1064nm), semiconductor side pumped YAG laser, semiconductor end pumped YAG laser (1064nm), fiber laser (1064nm), CO2 laser (10.64um). Now, various lasers will be introduced and explained

Fiber laser:Its wavelength（1064nm）， The main laser brands in the domestic market include: Shuke, Chuangxin, Haifu, 26 Institute, Lianpin, and Beijing Jitai. The main imported products are IPG from Germany.

CO2 laser:According to wavelength, it can be divided into:10.64um10.2um, 9.3um, etc. Generally, 90% of CO2 laser marking machines on the market use lasers with wavelengths of10.64um.There are not many manufacturers in China that produce lasers with a wavelength of 9.3um. Generally, CO2 laser marking machines use9.3um wavelength lasers are all imported,The domestic manufacturers of CO2 lasers mainly include Nanjing Chenruida and Beijing Dawei laser marking machine enterprises, which purchase the most, while imports mainly refer to manufacturers such as Datong and Xinrui;

Ultraviolet laser:According to wavelength, it can be divided into 355um. The ultraviolet laser has a very small focused spot, which can greatly reduce the mechanical deformation of materials and has a small impact on processing heat. Because it is mainly used for ultra-fine marking and engraving, it is particularly suitable for applications such as food and pharmaceutical packaging material marking, micro hole drilling, high-speed division of glass materials, and complex graphic cutting of silicon wafers. The main domestic manufacturers of ultraviolet lasers are Huari, Ruifengheng, Delong, andYinggu and others, asThe most commonly purchased laser marking machine by enterprises
