THERMAL EFFECTS IN ORTHORHOMBIC YAP CRYSTALS
SHEN HONG-YUAN (Fujian Institute of the Structures of Matter, Academia Sinica)
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.
