Abstract:The operation of a flashlamp pumped the neodymium doped potassium gadolinium tungstate(Nk:KGd(WO4)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.
Keywords:Flashlamp pumped  Nd:KGW crystal  Laser
