研制了一台用声光Ｑ开关内腔倍频Ｎｄ：ＹＡＧ激光泵浦的掺钛蓝宝石激光器，其最大平均输出功率达７．７１Ｗ。７．４Ｗ时的转换效率为３３％。通过数值模拟研究了该激光器的工作特性，其结果与实验基本相符。
A titanium-doped sapphire laser pumped by an acousto-optic Q-switched intracavity frequency doubled Nd: YAG laser was developed, with a maximum average output power of 7.71W. The conversion efficiency at 7.4W is 33%. The working characteristics of the laser were studied by numerical simulation. The results are in good agreement with the experiment.
