Our simulation results show that the position of the crystal inside its holder has a significant impact on the maximum induced stress. Accordingly, the optimum position of the crystal in the holder is first introduced and, it is shown, induction stress reaches the lowest value at 400 microns outside the holder that this position is independent of the pump laser power. It is also proven that optimum positioning is more important for chamfered laser crystals. CP - IRAN IN - LG - eng PB - opsi PG - 1053 PT - Research YR - 2020
