ABSTRACT We report a nonlinear-mirror mode-locked diode-pumped solid-state Nd:GYSGG laser operating at 1061 nm. The nonlinear mirror comprises a periodically poled LiNbO3(PPLN) crystal and a dichroic mirror. Continuous-wave mode-locked laser with an output power of 450 mw is obtained under a diode pump power of 5.5 W at 808 nm. The repetition rate of the mode-locked laser is 97.1 MHz and the bandwidth of spectral is 1.3 nm. Considering the group velocity mismatch (GVM) of PPLN, we estimate the minimum pulse width is about 9 ps.

摘要 我们报告了一种工作在 1061 nm 的非线性镜面锁模二极管泵浦固态 Nd:GYSGG 激光器。非线性反射镜包括一个周期性极化的 LiNbO3(PPLN) 晶体和一个分色镜。在808 nm的5.5 W二极管泵浦功率下获得输出功率为450 mw的连续波锁模激光器。锁模激光器的重复频率为97.1 MHz,光谱带宽为1.3 nm。考虑到 PPLN 的群速度失配 (GVM),我们估计最小脉冲宽度约为 9 ps。
