The thermal effects arising from the lasing process in orthorhombic YAP crystals have been discussed theoretically in this paper. Mathematical expressions have been given for the thermal distribution, stress-strain distribution, birefringence and thermal lens effect of the YAP crystals as well as the isogyre pattern of a YAP rod placed between crossed polarizers. It is shown that calculated results agree qualitatively with the observed thermal effects.
