四面体光学棱镜

Pyramid Optical Prisms

讨论了四面体光学棱镜(包括立方体角锥棱镜)的几何光学特性和光偏振特性,给出了四面体光学棱镜内空间走向光线的传播和反射规律;叙述和证明了立方体角锥棱镜的光学不失调特性和光偏振特性.设计了两组由四面体光学棱镜构造的单块非平面单向行波环形激光谐振腔,分别用于LD泵浦产生1.064μm和1.319μm两个波长的单频固体激光.给出了谐振腔的设计方法和实验结果.

Light ray geometry and polarization properties of pyramid optical prisms (including corner cube prisms) are discussed. Spatial ray traces inside the prisms and the light reflection characteristics are discribed in detail. The misalignment insensitivity and light polarization property of corner cube prisms are investigated. Two groups of monolithic nonplanar unidirectional traveling wave ring laser resonators are constructed using pyramid prisms. The designed resonators are used for LD pumped solidstate lasers to generate 1064 μm and 1319 μm single frequeney lasers. Method of designing pyramid resonators and the experimental reasults are presented.
