本文简述闪光灯泵浦的掺钛宝石激光器的发展状况和应用前景，描述了我们研制成功的实用型四灯泵浦的掺钛宝石激光器实验装置和实验结果．实验中采用本单位生长的掺钛宝石棒尺寸为φ１００×１６０ｍｍ，有效泵浦长度为１５２ｍｍ；平凹激光谐振腔，腔长３５ｃｍ；自制的四灯聚四氟乙烯聚光筒，漫反射效率９８％；四灯串联泵浦，闪光脉宽为１０μｓ．当输入能量为３２０Ｊ时，激光输出达到１．７Ｊ，激光效率０．６％，重复频率１Ｈｚ，可调谐范围７００～１０００ｎｍ．
This paper describes the development and application of flash-pumped Ti-doped sapphire lasers, and describes the experimental device and experimental results of a practical four-lamp-pumped Ti: sapphire laser. In the experiment, the size of the titanium-doped sapphire rod grown by this unit is φ100 × 160mm, the effective pump length is 152mm, the plano-concave laser resonator has a cavity length of 35cm, a self-made four-lamp polytetrafluoroethylene condenser tube with a diffuse reflection efficiency of 98 %; Four-lamp series pump, flash pulse width of 10μs. When the input energy is 320J, the laser output reaches 1.7J, the laser efficiency is 0.6%, the repetition frequency is 1Hz and the tunable range is 700 ~ 1000nm.
