CO2 laser has been paid close attention to for nearly 50 years since its birth. CO2 laser is a kind of gas laser with CO2 as working material. CO2 laser is a kind of important gas laser. At present, the research direction of CO2 laser mainly focuses on the following aspects:
No. 1, high power CO2 laser.
Compared with the solid-state laser, the power of CO2 laser is very high, but on the whole, the power of CO2 laser is still relatively low. In 1964, through the use of N2, the conversion power reached 3%; in 1965, through the use of co2-n2-he gas mixture, the conversion power reached 6%. So far, its maximum power will not exceed 60%. Many companies are discussing the power improvement. Taking Datong company as an example, the power of CO2 laser has reached about 60%. Most of the domestic companies with better research and development have military background, and now the power is close to the international level.
Second, high power CO2 laser
High power has always been the goal of the military. In this regard, the research level of some domestic military enterprises is still relatively backward. The U.S. Air Force was the first to study high-power CO2 lasers. In 1975, the 11th anniversary of the birth of CO2, the US Air Force Medical developed a CO2 laser with a power of 30kW. In 1988, the output power of CO2 laser has reached 380kW. Now, according to some data released by the U.S. military, the output power of the CO2 laser has reached the level of 10 MW.
Third, small volume multi-function CO2 laser.
At present, most of the CO2 lasers have single function and can only be engaged in a very specific operation. We know that the CO2 freckle laser and CO2 hair removal laser used in large hospitals are very large in volume, but the structure is basically the same. The use of multi-purpose CO2 laser, the occupation of small volume, and the price is relatively low. In this respect, domestic research is at the international level, of course, most of the research institutions have hospital settings.
Fourth, industrial technology uses lasers
CO2 laser plays a leading role in laser processing. It is widely used in cutting, marking, engraving and cleaning. The quality and power of output laser have very clear requirements. Therefore, CO2 laser in industry should have high quality laser beam and stable output power, such as carbon dioxide cutting machine, carbon dioxide marking machine and other laser equipment, which play an irreplaceable role in the industry
Laser has been widely used in optics, medicine, atomic energy, geography, geography, ocean and so on. It marks the beginning of the new technological revolution. If you compare the pre history of laser deployment with that of electronics and aviation, you have to realize that it is still the early stage of laser deployment, and more exciting prospects are coming.
