Abstract: | 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. |

Keywords: | laser technology Nd∶YVO_4 laser end-pumped laser diode doped concentration |
