摘要
利用声光Q开关中衍射效率最大的位置调Q可以发挥其最大性能的特点,研究声光Q开关晶体中超声场的空间分布,得到了晶体中衍射效率的空间分布,从而确定了衍射效率最大的位置,并在实验中得到了与理论分析一致的结果。该结果对大功率激光二极管泵浦调Q固体激光器中Q开关的调节具有实际意义。
Acoustooptic can be optimized by utilizing the site of maximum diffraction efficiency to Qswitch.Distribution of diffraction efficiency in acoustooptic crystal is obtained by studying distribution of ultrasound field. thereby, the site of maximum diffraction efficiency is found, and the same outcome is gained in the experiment. It is of benefit to the attainment of optimal parameters (the peak power, pulse width,etc) in DPL.
