Abstract

The presented data are the results of the development of the continuous electric-discharge CO₂ laser with the cross discharge and convective cooling of the active medium, with the power up to 14 kW. Extended disc fans are used for gas pumping, they are heat-exchangers at the same time. Preliminary results of gas flow-rate, heat-exchange and energy characteristics are reported. Some experimental results of laser cutting of thick sheets are given as well as the results of the numerical and experimental simulation of the laser cutting gas-dynamics.
