1.YAG solid-state laser cutting machine has a low price and good stability, but can although the efficiency is low,generally less than 3%, the current product output power is mostly below 600W, due to the small output energy, mainly used for punching and spot welding and cutting of thin plates. Its green laser beam can be applied in the case of pulses or continuous waves, with a short wavelength, good concentration of light suitable for precision processing especially under the pulse for hole processing is most effective, can also be used for cutting, welding and lithography, etc. YAG solid laser cutting machine laser wavelength is not easily absorbed by non-metals, so can not cut non-metallic materials, and YAG solid laser cutting machine needs to address is to improve the power supply Stability and life, that is, to develop a large-capacity, long-life light pump to stimulate the light source, such as the use of semiconductor light pump can make a substantial increase in energy efficiency.

1.1 Main advantages

It can cut other laser cutting machine can not cut the aluminum plate, copper plate and most of the non-ferrous gold session materials, machine purchase price is cheap, low cost of use, simple maintenance, most of the key technology has been learned by domestic enterprises to grasp, the price of accessories and maintenance costs are low, and machine operation and maintenance is simple, the quality of workers do not require high.

1.2 Main market positioning

Cutting thickness is less than 8mm, mainly for self-use small and medium-sized enterprises and processing requirements are not particularly high most of the sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration, advertising and other industry users, gradually replace the line cutting, CNC punching machine, water cutting, small power plasma and other traditional processing equipment.

The CO2 laser cutting machine can cut carbon steel up to 20mm, stainless steel up to 10mm and aluminium alloy up to 8mm. CO2 laser has a wavelength of 10.6um, which is easily absorbed by non-metallic materials such as wood, acrylic, PP and organic glass, but the photoelectric conversion rate of CO2 laser is only about 10%. The CO2 laser cutting machine is equipped with a nozzle that blows oxygen compressed air or inert gas N2 at the exit of the beam to improve the cutting speed and the smoothness of the cut. In order to improve the stability and life of the power supply, for CO2 gas lasers to address the discharge stability of high-power lasers. According to the international safety standard laser hazards are divided into 4 levels, CO2 lasers belong to the least hazardous level.

2.1 Main advantages

 High power, generally between 2000-4000W, can cut full size stainless steel, carbon steel and other conventional materials up to 25 mm, as well as aluminium plates up to 4 mm and acrylic plates up to 60 MM, wood material plates, PVC plates, and is very fast when cutting thin plates. In addition, due to the continuous laser output of the CO2 laser, the cut section is very smooth when cutting.

2.2 Main market position

6-25 mm thick plate cutting process, mainly for large and medium-sized enterprises and part of the pure external processing of laser cutting processing enterprises, but due to its laser maintenance wear and tear, host power consumption and other insurmountable factors, the market is in a significantly shrinking state.
