提出全新的全固态双镜环行行波激光器.其谐振腔仅由两个凹面镜组成,其中一面镀制在激光介质的凹面上,产生的激光束沿着在此二面镜之间的三维回路传播.已经实现了多种行波模式和多点泵浦的双镜环行行波激光器.实验结果表明此类激光器有最简单的结构和稳定的输出,可用以研制高性能的单频激光器、短腔锁模激光器和低热透镜效应的高功率激光器.
A completely new type of solid-state round travelling-wave laser was presented. The resonator consists of only two concave mirrors and one of them is coated on the curved surface of the laser material. Between the mirrors the laser beam travelled in a closed 3-dimensional loop.Oscillations of many kinds of round travelling-wave laser modes have been observed , and lasers pumped at two defferent points on the active material have been developed. The experimental results indicates that the novel laser has most simple structure and very stable output. Using this design, high-efficient laser, single-frequency laser and mode-locked laser with short cavity length can be developed.
