摘　　要：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．In this paper the trend of development and applications of flashlamp-pumped Ti:sapphire lasers are briefly reviewed, and experimental setup and results of a Ti:sapphire laser pumped by four fiashlamps are presented. The Ti:sapphire rod used is Czochralsky-grown in our institute, and cut for of φ10×160 mm, with effective length of 152 mm. The resonator is a 35 cm-long flat-concave arrangement.The cavity is made of Teflon powder with defused reflectivity of 98%. The discharge pulse-width of the lamp-series is 10 μs. When input energy is 320 J, the laser produces 1.7 J, with efficiency of 0.6%, repetition rate of 1 Hz,tunable range of 700-1000 nm.
