摘要
利用闪光灯作为抽运源研究了Nd:GdVO4晶体的脉冲激光性能.激光晶体样品尺寸为4 mm×4 mm×6 mm.当输出镜透过率T=15%,抽运能量为 6.32 J时,激光器静态输出能量为 31.7 mJ.对T=7%的输出镜,抽运阈值为 0.13 J.用厚度为 1.5 mm,小信号透过率为 54.7%的Cr4+:YAG晶体片实现了激光器的被动调Q运转,测得动态和静态激光能量输出之比约为1:3.在T=15%的输出镜透过率下,当抽运能量为 3.89 J和 6.32 J时,分别得到了脉冲宽度为 48.0 ns和 39.2 ns的单脉冲输出.
Abstract
Pulse laser performance of Nd∶GdVO 4 crystal is investigated by using xenon-flash lamp as pump source. The dimension of the laser crystal sample is 4 mm×4 mm×6 mm. With output coupler transmission of T=15%, static output energy of 31.7 mJ is obtained at the pump energy of 6.32 J. For T=7% output coupler, the pump threshold of the laser is 0.13 J. The passively Q-switched operation is achieved by using 1.5 mm thickness Cr 4+∶YAG wafer with small-signal transmission of 54.7%. The dynamic-static laser output ratio is about 1:3. With T=15% output coupler, single laser pulses with duration of 48.0 ns and 39.2 ns are acquired at the pump energy of 3.89 J and 6.32 J, respectively.
