The crossed Porro prism configuration improves the stability of the alignment of the laser resonator; however, the resultant phase shift alters the characteristics of the electrooptical Q-switch. An analysis of the operational characteristics, such as variable outcoupling, extinction ratio, and prelasing boundaries, is presented along with experimental data. An electrooptically Q-switched Nd:YAG laser with a crossed Porro prism resonator, which successfully withstands severe physical environments, has been developed and demonstrated.
交叉波罗棱镜配置提高了激光谐振器对准的稳定性；然而，由此产生的相移改变了电光Q开关的特性。文中给出了对诸如可变输出耦合、消光比和预激射边界等工作特性的分析以及实验数据。一种具有交叉波罗棱镜谐振器的电光调Q Nd:YAG激光器已被研制并展示，它能成功经受恶劣的物理环境。
