| Abstract: | The effect of dopped concentration and crystal length on the performance of Nd:YVO4 was analysized firstly,then a fiber-coupled diode-end-pumped Nd:YVO4 laser with a Nd:YVO4 crystal of 0.3at% dopped concentration and 10mm length was reported in this paper. 14. 85W of CW TEM00 mode output was obtained at a pump power of 27. 365W, resulting in an optical conversion efficiency of 60.49% ,and a slope efficiency of 64.5%. |
