LD准连续泵浦的Nd：FAP固体激光

Quasi-CW LD-pumped Nd: FAP laser

用脉宽为４００μｓ，峰值功率为１３１３ｍＷ，重复频率为５０Ｈｚ的激光二极管泵浦自行研制的Ｎｄ：ＦＡＰ晶体，获得平顶峰值功率为１５７ｍＷ的激光输出。泵浦阈值功率１１７ｍＷ，斜率效率２２．５％。

Nd:FAP crystal was pumped by a SDL-2480-H1 laser diode with pulse power of 1313 mW and pulse width of 400 μs at a repetition rate of 50 Hz.The threshold power was found to be 117 mW,and the output/input characteristics were demonstrated.
