本文简述闪光灯泵浦的掺钛宝石激光器的发展概况和应用前景，叙述了用自己研制的高能量短脉冲同轴闪光灯泵浦的掺钛宝石激光器实验装置和实验结果。实验中采用本单位用提拉法生长的掺钛宝石棒，其尺寸为Φ１０×１６０ｍｍ，有效泵浦长度为１５２ｎｍ，棒的两端面镀增透膜；采用平凹型激光谐振腔，腔长３６ｃｍ；闪光灯放电脉宽为１０～１２μｓ。当泵浦输入能量为６１２Ｊ时，激光输出能量最高达到３．２Ｊ，激光能量转换效率约为０．５％。 This paper describes the development and application prospects of flash-pumped Ti-doped sapphire laser, and describes the experimental device and experimental results of Ti-doped sapphire laser pumped by high-energy short-pulse coaxial flash lamp. In the experiment, the Ti-doped sapphire rod grown by Czochralski method has the size of Φ10 × 160mm and the effective pump length of 152nm. Both ends of the rod are coated with anti-reflective coating. The plano-concave laser resonator with a cavity length of 36cm, Flash discharge pulse width of 10 ~ 12μs. When the pump input energy is 612J, the laser output energy reaches up to 3.2J, and the laser energy conversion efficiency is about 0.5%.
