The asymmetric thermal distortion of output window of high power CO2 lasers and its causes, as well as the resonator misalignment, a consequence of this kind of distortion, were investigated both theoretically and experimentally in this paper. A preliminary theoretical explanation of the misalignment was given, which reminded the importance of the realisation of uniform cooling.
