An electro-optically Q-switched Nd:YAG laser resonator that uses two end prisms placed orthogonally perpendicular to each other has been designed. This configuration improves the stability of the resonator and does not alter the characteristics of the electro-optical Q switch. The outcoupling ratio of the cavity is optimized by a change in the azimuthal angle of a phase-matched Porro prism placed at one end of the cavity. The prism placed at the other end of the cavity is designed so that it introduces a phase change of II, regardless of its orientation and index of refraction, resulting in a more efficient and stable cavity.
设计了一种电光调Q Nd:YAG激光谐振器，该谐振器使用两个相互正交放置的端面棱镜。这种配置提高了谐振器的稳定性，并且不会改变电光调Q开关的特性。通过改变置于腔一端的相位匹配波罗棱镜的方位角来优化腔的输出耦合比。置于腔另一端的棱镜设计成无论其取向和折射率如何，都会引入π的相位变化，从而形成一个效率更高且更稳定的腔。
