| 摘 要： | 为了实现了高重复频率声光调Q运转,通过分析掠入射激光器中的等效抽运光模式,对掠入射激光器的掠入射角度进行了优化,获得重复频率大于2MHz的声光调Q TEM00基模的实验输出.理论分析和实验结果表明,掠入射激光器存在一个优化的掠入射角度可以获得尽量小的抽运光模式横截面积,有利于激光器获得高增益和实现高重频运转.

| Abstract: | The grazing-incidence angle in grazing-incidence lasers was optimized for high repetition rate acousto-optical Q-switch by calculating the equivalent pump mode cross-section area.High repetition rate(>2MHz) acousto-optically Q-switched TEM00 output was obtained.It is shown from the results that there is an optimum grazing-incidence angle which is beneficial to high repetition rate operation in grazing-incidence laser. |
