摘要：

The switch-losses of one Q-switch, two Q-switches in acousto-field perpendicular or parallel are analyzed. According to the theory of acousto-optic (AO) interaction, the formulas of diffraction loss of two AO Q-switches. which acousto-field are perpendicular or parallel one another, in Raman-Nath diffraction are derived. The power divider for ensuring two AO Q-switch synchronization and effective power driving is designed. The calculation results are satisfied with Nd:YAG laser experimental results. It is shown that the switch-loss of two AO Q-switches, which acousto-field are perpendicular each other, is nearly three times as large as one AO Q-switch's, one time larger than the two AO Q-switches which acousto-field are parallel.
