摘　　要：报道了用闪光灯泵浦的掺钕的钨酸钆镓 ( Nd3 + :KGd( WO4 ) 2 )激光器 .在重复频率1 Hz,脉宽 1 2 0μs的灯泵下 ,测量了不同透过率下激光输出能量 ,获得最大输出能量 3 84m J,斜率效率 1 .0 % ,外推阈值 0 .54 J.在调 Q运行时 ,Nd∶KGW晶体的斜率效率为 0 .1 6% ,最大输出能量 46mThe operation of a flashlamp pumped the neodymium doped potassium gadolinium tungstate(Nk∶KGd(WO 4) 2) laser is reported in this paper.Output energy has been measured at 1Hz repetition rate and 120μs pulse duration of flashlamp for different output mirror transmission in free-running operation.The maximum output energy of 384mJ with the slope eficiency 1.0% is obtained,and the extrapolated threshold is 0.54J In Q-switched mode,the slope efficiency has been determined to be 0.16% and the maximum output energy is 46mJ
