摘要
运用ＡＢＣＤ 律及自再现条件对钛宝石线性腔的折叠角进行了优化，从而大大提高了钛宝石晶体中光束束腰的耦合效率同时实验上对连续钛宝石激光器进行了研究，采用２０ｍ ｍ 长的钛宝石晶体和１０％ 输出耦合镜，并运用优化后的折叠角，最终用全线氩离子激光器泵浦的连续波钛宝石激光器的斜率效率高达３４２％ ，在泵浦功率为７７Ｗ 下。
The folded angle of Ti∶sapphire linear cavity is optimized with the ABCD law and the self mantaining condition The coupling efficiency of beam waist in the Ti∶sapphire crystal is raised remarkably At the same time,the continuous wave Ti∶sapphire laser is studied experimentally 34 2% high slope efficiency of continuous wave Ti∶sapphire laser pumped by all line Ar + laser is obtained,with 20mm Ti∶sapphire crystal and 10% output coupling mirror,also using the optimized folded angle With pumping power of 7 7W,the output power of continuous wave Ti∶sapphire laser is 1 89W
