查询词典 a quarter

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.
