The commercial lasers with power 20 kW and up are created by scaling of well-developed electrodischarge kilowatt CO2 laser with circulating of gas. However, there occurs two negative moments: loss of the optical beam quality and significant increase of laser cost. The first moment is connected not so much with increase of laser beam path between resonator's mirrors as with quantum efficiency of CO2 molecule, which is 0.41, and also with conversion of irremoved vibrational energy to heat in a resonator. The cost of lasers with power 10 kW and higher is considerably increased in scaling of kilowatt CO2 lasers. This is associated with the necessary increase of consumption of active medium, resulting not only in a change of circulating system, but in a change of regeneration system, source of power supply, cooling system, system of extracting radiation, etc. as well.
