In recent years, market demand has increased by several times per year. At present, there are three types of medium and high power 300w 400w 500w 600w 800w 1000w CO2 laser tube on the market: one type is RF excitation lasers, which are expensive and complicated in technology. Only a few companies in the US and Germany can produce them; the second category is axial-block lasers, due to their production processes and technologies. The reason for the route is that only high power has the cost performance and competitive advantage, and the cost of use is also high. The third type is the folded CO2 medium power laser tube made of pure glass. Due to the glass characteristics, its stability is not good. It has also failed to break through kilowatts of power, and there is still some distance from the market demand.
