Abstract :
We have investigated thermally-induced-birefringence effect in Nd:YAG ceramics and found that depolarization loss of highly Nd3+-doped ceramics is much larger than that of conventional Nd:YAG single crystals even at the same absorbed pump power under nonlasing condition. In this paper, however, we report that drastic reduction of depolarization loss is realized in highly Nd3+-doped YAG ceramics by laser oscillation.
