Abstract

The main difficulty for these lasers is the thermal effects which induced by thermal stress. The stress distribution takes a very important part in a high average power laser. The optical distortions which include thermal focusing, stress induced biaxial focusing, stress induced birefringence can be known easily if the stress distribution is already known clearly. In order to know the stress distribution, the temperature distribution is discussed at first because the nonuniform temperature distribution is the main reason which induces the thermal stress. Our discussion mainly aimed at the the stress distribution in the high average power lasers, especially in annular geometry lasers.
