Abstract

We report a synchronously-pumped femtosecond diamond Raman laser operating at 890 nm with a slope efficiency of 32%. Pumped using a mode-locked Ti:Sapphire laser at 796 nm with a pulse duration of 194 fs, the bandwidth of the Stokes output was broadened to enable subsequent pulse compression to 65 fs using a prism-pair. Modelling results provide an understanding of the physical mechanisms involved in the Raman conversion of femtosecond pulses, supporting an in-depth characterization of these ultrashort pulsed lasers.

摘要

我们报道了一种同步泵浦的飞秒金刚石拉曼激光器，其工作波长为890nm，斜率效率为32%。该激光器由一台锁模钛宝石激光器在796nm波长、脉冲持续时间为194fs的条件下泵浦，斯托克斯输出的带宽得到展宽，从而能够使用棱镜对将后续脉冲压缩至65fs。建模结果有助于理解飞秒脉冲拉曼转换所涉及的物理机制，为深入表征这些超短脉冲激光器提供了支持。
