Abstract

We report the first cw intracavity crystalline Raman laser operating at the second-Stokes wavelength. Approximately 950 mW emission is obtained at 1308 nm from a Nd:GdVO(4) self-Raman laser, with an overall (diode to 1308 nm) conversion efficiency of 6.8%. By intracavity sum-frequency mixing the first- and second-Stokes lines, 1027 mW emission at 620 nm is demonstrated with an overall (diode-to-visible) conversion efficiency of 4.9%.

摘要

我们报告了首例连续波腔内晶体拉曼激光器，其工作波长处于第二斯托克斯范围。从 Nd:GdVO(4) 自拉曼激光器中获得了约 950 mW 的 1308nm 发射，整体（从二极管到 1308nm）转换效率为 6.8%。通过腔内和频混合第一和第二斯托克斯线，在 620nm 处实现了 1027mW 的发射，整体（从二极管到可见光）转换效率为 4.9%。
