用点籽晶快速生长法在不同温度区间生长了四块氘含量60% DKDP晶体,观察了不同温度下晶体生长过程,同时测量了晶体的透过光谱、摇摆曲线和1053 nm激光损伤阈值。结果表明,在高温区间晶体生长外形优于低温生长的晶体。不同温区晶体的透过光谱并无明显变化,但是随着生长温度的降低,晶体的结构完整性变差,1053 nm激光损伤阈值降低。

Four 60% DKDP crystals were grown at different temperatures using point seed technique. The growing process was observed. The properties including optical transmittance, rocking curve and laser induced damage threshold were measured. The results show that the morphology of crystal grown at high temperature is more perfect than that grown at low temperature. The effect of growth temperature on optical transmittance for these crystals is slight. However, the structure perfection and the laser induced damage threshold decrease with the decrease of growth temperature.
