High power CO 2 and CO lasers for industrial applications in TRINITI

The CW and HRR facilities developed at the Prospective Research Department of TRINITI and their application for various laser - matter interactions are discussed. The high power lasers are as follows: the CW self - sustained discharge CO 2 lasers LT-1 (output power up to 5 kW) and PM-1 (output power up to 85 kw); the e-beam sustained discharge HRR CO 2 lasers: with traditional gas mixture composition at atmospheric pressure in the discharge chamber (output power up to 100 kw) and with gas mixture of atmospheric air and 5% C0 2 at reduced pressure (output power up to 30 kw); the e-beam sustained discharge cryogenic CO lasers: with a subsonic gas flow CW laser (average power ~85 kw) and with supersonic flow of the active mixture quasi-CW laser (specific output energy up to 40 Jg -1 and efficiency ~14%). These laser facilities are used for studies on interaction of laser radiation with different materials, metals, rocks, etc.
