Abstract
Modes of stable resonator, which consist of thermal distorted flat and concave mirror, were investigated with Fox-Li iteration. The amplitude and phase distributions on output mirror were also presented. In order to erase the mode's distribution, the thermal distribution of both mirrors should be less than 1/20 wavelength. It is also pointed out that there are more serious mirror thermal distortion in fringe cooling mirror in high power laser and laser beam quality was lowered badly. If the mirror distortion is larger than 1/10 wavelength no stable fundamental mode can be attained.
