摘要：

The transformation course of a quarter-waveplate s rotating polarization plane of elliptically polarized light is deeply analyzed by the Jones vector transformation. 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. Furthermore, the experimental result is well in accord with theoretical analysis.
