Abstract

A 20 kW class CW CO laser has been designed and constructed to demonstrate the capability of CO laser as a high power laser and to study its industrial applications.In this system, a transverse self-sustained dc glow discharge is applied as ex6itation, and a laser gas miXture is cooled and controlled through heat exchangers operating with liquid N2 and it's temperature is controlled by heaters.Using a stable resonator, 21 kW laser output was obtained with an electrical conversion efficiency of 22%for a mixture of CO/N2/He/O2=6/16/78/0.2 (%) at 150 K, 40 Torr and 22 m/s.
