Abstract
The aims of work were theoretical analysis of thermo-optic effects occurring inside Nd:YAG ceramic gain elements and its experimental verification under high heat loads. For theoretical analysis we have applied the semi-analytical models based on thermo-elasticity theory [1,2] and compared it to results obtained applying COMSOL Multiphysics software. Thermally induced distortions, stresses and birefringence were calculated for several gain elements of rod, disk and slab shapes.
