Laser output properties of (Nd, Tb, Ce)：YAG crystal

(Nd,Tb,Ce):YAG crystal is a new laser material developed recently.In this paper,the comparission research on the laser output properties, for example laser output energy, beam divergence angle and beam quality factor M2, with other laser crystals, such as present Nd:YAG and (Nd,Ce):YAG crystal, is reported.The experimental results show that the pulsed laser effectiveness of (Nd,Tb,Ce):YAG crystal may not be lower than other crystal's, but the thermal distortion and the thermalstability of(Nd,Tb,Ce):YAG crystal are obviously better than other crystal's,under the condition ofblowing cooling. The crystal can be used in high repitation frequency laser.
