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, 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 show that two ao q - switches, which acousto - field are perpendicular each other, switch - loss is nearly one times larger than one ao q - switch, one of third larger than the two ao q - switches which acousto - field are parallel
從理論上對聲光器件衍射損耗作了分析與計算，研究了二維雙聲光器件對提高衍射損耗效率的影響，在實驗中採用二維雙聲光組合器件提高聲光器件的對nd ： yag激光器的關斷能力，較之單聲光的關斷能力提高了一倍左右，而對于平行雙聲光也提高了30左右，並設計了聲光驅動功率分配器以驅動雙聲光器件達到同步，消除了激光輸出的多脈沖現象，提高了脈沖列的輸出功率。 -
By solving the christoffel equation, the relationship between velocity and angles is obtained, and the ultrasonic inverse velocity curve is illustrated. the dixon equations of ao diffraction on the xoz and yoz planes in ln crystal have been applied to obtain the geometric relationships of acousto - optic interaction. therefore, the beam steering theory is proved to be a possible way to do the optimum design of ln anisotropic acousto - optic deflector. the detailed parameter data and the figures on the xoz and yoz planes with the angle of incidence of - 5 degree are shown up, which will contribute to the desigh of aod
