Thermal distortion of mirrors caused by high power CW laser radiation and pressure distortion by water-cooled back pressure have been measured using a Twyman-Green interferometer.
In this laser the discharge tube with an inside diameter of 8mm and discharge length of 300mm is made of water-cooled segmented aluminium disks.

Dynamic variation of thermal distortions and depolarization losses of heat capacity laser is also analyzed. The simulation results are compared with those of continued water-cooled rod laser.
