internal reflector

, the coaxis resonator with a compound total internal reflection (TIR) prism and a mirror, half o f which has reflectivity R and the other half has a high-reflection coating (R/HR mirror), and the folded resonator with a compound TIR prism, a normal triple prism and a R/HR mirro.

从对正三棱锥和其它偏振元件的分析出发，对板条固体激光器用两类新型棱镜腔，即共轴复式全内反射棱镜－半反／全反阴阳镜腔和复式全内反射校镜－正三棱锥－阴阳镜折迭腔的偏振特性作了详细的理论和实验研究。
