Carbon dioxide laser in 1964 for the first time to use their wavelength 10.6μm. Because this is a very efficient laser, as a business model for its conversion efficiency reaches 10%, so the carbon dioxide laser is widely used in laser cutting, welding, drilling and surface treatment. As business applications up to 45 kilowatts of laser, which is currently the most powerful laser material processing. Carbon dioxide laser is a molecular laser. The main material is carbon dioxide molecules. It can show a variety of energy state which depends on its shape and rotation of the vibration may be. Basic energy mesh in Figure 1. Carbon dioxide gas is mixed in the low-pressure gas release caused due to electron (usually 30-50 torr) to form a plasma (plasma). As Maxwell - Boltzmann distribution law says, in the plasma, the molecules show a variety of excited states. Some will show a high-energy state (00o1) which showed asymmetric swing state. When the hollow wall collision or natural distribution, this molecule will be occasional loss of energy. This high energy state by the natural distribution of drops to form symmetrical swing (10o0) and may spread to any direction emitted photon (a light beam having a wavelength 10.6μm). By chance, one that photons propagate along the optical axis downward swing in the resonance cavity will also mirror. In general, the carbon dioxide laser working substance is carbon dioxide, helium, nitrogen, a mixture consisting. Nitrogen was used as a buffer gas as well as its molecular resonance stimulation energy transmitted to the carbon dioxide molecules. Because relaxation levels (01110) is the bottleneck, the role of helium is as a heat sink to transfer energy to the level of (01110) to the helium atom.

As business applications up to 45 kilowatts of laser, which is currently the most powerful laser material processing. CO2 laser is a gas laser more important. This is because it has some of the more prominent advantages: First, it has a relatively large power and relatively high energy conversion efficiency. CO2 lasers are generally closed tube can have tens of watts of continuous output power, which is far more than the other gas lasers, horizontal-flow CO2 laser excitation of electricity may have hundreds of thousands of watts of continuous output. Further lateral atmospheric CO2 laser, the pulse output from the energy and power have also reached a high level, comparable with solid-state lasers. CO2 laser energy conversion efficiency up to 30 to 40%, which exceeds the typical gas lasers. Second, it is the use of CO2 molecules vibration - rotation transitions between energy levels, there is relatively rich spectrum in the vicinity of 10 m have dozens of lines of laser output. High-pressure CO2 lasers found in recent years, and even can be done from 9 to 10 microns continuously tunable output. Third, it is just the output of the band atmospheric window (ie atmospheric transparency at this wavelength is higher). In addition, it also has a high optical output beam quality, good coherence, line width, etc. stable. So it has many applications in the national economy and national defense, such as used in processing (welding, cutting, drilling, etc.), communications, radar, chemical analysis, laser-induced chemical reaction, surgery and so on. Lateral excitation power carbon dioxide laser, mainly for laser welding, laser cutting, laser heat treatment. In the automotive industry, steel industry, shipbuilding industry, aviation industry, machinery industry, metallurgical industry, metal processing and electrical manufacturing, and other fields are widely used.
