	1	Superior performance of a 2 kHz pulse Nd:YAG laser based on a gradient-doped crystal显示文摘Herein,we report a homemade new Nd:YAG crystal rod that contains a gradient dopant of 0.39–0.80 at.%Nd3+ from end to end,achieving superior performance of a 2 kHz Nd:YAG pulse laser at 1064 nm. The optical-tooptical conversion efficiency reached 53.8%,and the maximum output power of the laser was 24.2 W,enhanced by 35.9% compared with a uniform crystal rod with the same total concentration of Nd3+. Significantly,our experiments revealed that the gradient concentration crystal produced a relatively even pumping distribution along the rod axis,greatly reducing the temperature gradient as well as having a smaller thermal effect. The pump and thermal distribution smoothing obviously improved the features of laser oscillation and output.
