Abstract

We report a diode-pumped Q-switched Nd:YAG-KGW Raman laser operating in two-color modulation. The output wavelength can be switched between 1159 nm and 1177 nm using an E-O switch, and the Raman output modulated in spectra-time domains was achieved. Raman pulse energy up to 114 mJ at 1177 nm and 98 mJ at 1159 nm were obtained respectively, corresponding to an overall Diode-Stokes conversion efficiency of 15.3% at 1177 nm and 13.2% at 1159 nm.

摘要

我们报道了一种工作在双色调制模式下的二极管泵浦调Q Nd:YAG-KGW拉曼激光器。利用一个电光开关，输出波长可在1159nm和1177nm之间切换，并实现了拉曼输出在光谱-时域的调制。在1177nm处获得了高达114mJ的拉曼脉冲能量，在1159nm处获得了98mJ的拉曼脉冲能量，对应于在1177nm处总二极管-斯托克斯转换效率为15.3%，在1159nm处为13.2%。
