摘　　要：报道了闪光灯泵浦掺铬氟化铝钙锂（ＣｒＬｉＣＡＦ）可调谐、Ｑ开关激光器的实验结果。调谐范围为７３０～８５０ｎｍ，峰值波长为７８０ｎｍ。激光最大输出能量为１．６２Ｊ，斜率效率为０．８％，阈值为５０．４Ｊ。ＫＤ＊Ｐ晶体电光调Ｑ，单脉冲半宽度为４８ｎｓ，峰值功率为１．３×１０６Ｗ。In this paper, a tunable Q switched flashlamp pumped Cr 3+ ∶LiCaAlF 6 laser is introduced. The tuning range of a Cr 3+ ∶LiCaAlF 6 is determined to be at least 730￣850 nm. The free running lasing wavelenth of the Cr 3+ ∶LiCaAlF 6 is 780 nm. When the input pulse energy is 292 J, the highest output energy is 1.62 J. A slope efficiency is 0.8%. The threshold energy is 50.4 J. The Q switching of the Cr 3+ ∶LiCaAlF 6 is performed with a KD P crystal. The single pulse width is 48 ns and the highest output power is 1.3×10 6 W.
