摘　　要：本文主要报导用钛宝石进行长波段激光调谐的实验结果。钛宝石晶体（φ４×１１．５ｍｍ）置于四镜Ｚ形驻波腔内，由氩离子激光器全线轴向泵浦，激光波长由石英双折射滤光片调谐。在８Ｗ功率泵浦时，钛宝石激光器调谐范围是９０１．６ｎｍ到１０００．０ｎｍ；当泵浦功率为８．９Ｗ时，１００５．０ｎｍ处激光输出超过１５ｍＷ．９８０ｎｍ处钛宝石激光器的阈值为６．６Ｗ，斜率效率为３．７％；当泵浦功率为１０．５Ｗ时，激光连续输出达１５５ｍＷ。同时还对实验结果和双折射调谐器的设计进行了分析。The experimental results about long-wave band tuning characteristics with Ti:Sapphire crystal produced at home are reported. The Ti: Sapphire crystal (φ4×11.5mm ) put in the four-mirror folded standing wave cayity is axially pumped by Ar+ laser in all lines. The quartz birefringent filter is used to tune thelaser wayelength.The wavelength range of Ti:Sapphire laser is 90 1.6nm to 1000.0nm with 8W pump power;and the output power is larger than 150mW at λ=1005.0nm with 8.9W pump power. The laser threshold and the total slope effeciencyare 6.6 W and 3.7%at λ=980.0nm, respectively. Some discussions about the experimental results and the design of birefringent filter used in CW Ti:Sapphire laser are given as w ell.
