本文提出了一种交叉棱镜望远镜腔,并用该腔进行了重复频率YAG调Q激光实验.理论分析和实验表明,该腔的机械稳定性好,选模能力强,对激光工作物质的光学质量要求不高.用该腔组成的激光器很容易得到发散角小于1mrad、强度为10MW量级的激光束.

A new type of resonator called telescopic-crossed prism resonator is proposed and investigated on a repetitave YAG laser. Theoretical analyses and experimental rosula have showed that this resonator has a high mechanical stability and excellent transverse mode selectivity even if a YAG rod with moderate optical quality is used. By using this resonator, it is easy to obtain a beam which can give an output power of 10 MW andts divergence angle less than 1 mr.
