摘　　要：报道了利用掺杂浓度为 0 3at. % ,通光长度为 10mm的Nd∶YVO4晶体作为增益介质 ,带光纤耦合的激光二极管端面抽运的Nd∶YVO4激光器。在抽运功率为 2 7 36 5W时 ,获得了 14 85W的TEM0 0 模输出 ,光 光转换效率为6 0 4 9% ,斜率效率达 6 4 5 %。A fiber-coupled diode-end-pumped Nd∶YVO_4 laser with a Nd∶YVO_4 crystal of 0.3 at.-% dopped concentration and 10 mm length was reported in this paper. CW TEM_ 00 mode output of 14.85 W was obtained at a pump power of 27.365 W, resulting in an optical conversion efficiency of 60.49%, and a slope efficiency of 64.5%. The effect of dopped concentration and crystal length on the performance of Nd∶YVO_4 was also analyzed.
