| Abstract: | In This paper, the output characteristics of LD end-pumped Nd: YVO4 solid-state laser were researched by experiment, under various transparency rate of output mirror and different crystal size and different doped-concentration. The thermal focal length of crystals was also measured. When pumped power was 21W, the output laser of 8. 5W was realized, which was quasi-TEM00 mode and steady power, resulting in an optical conversion efficiency of 40. 5% and a slope efficiency of 59. 4%. |
