According to the principle of A-O interaction and quartz′s different characteristic in the direction of parallel and perpendicular acoustics field, with a quarter-wave plate being inserted in an AO Q-switch Nd∶YAG laser cavity between mirror and Q-switch, AO Q-switch′s Bragg diffraction efficiency formula is put out theoretically. Consequently, the conclusion has been drawn by calculating simulation that the ability of a single AO Q-switch′s switching CW Nd∶YAG laser is increased.

结合声光相互作用理论和声光介质熔石英在平行和垂直于声场的两个方向具有不同声光优值的特性，理论推导了腔内引入四分之一波片后声光Q开关的布喇格衍射效率公式，计算模拟得出引入四分之一波片能够有效地提高声光Q开关关断连续Nd∶YAG激光的能力。
