Abstract

We demonstrated an efficient MoS₂-based eye-safe passively Q-switched Nd:GGG laser under 880 nm LD pumping. The maximum average output power was about 1.05 W with a slope efficiency of about 7.0%. The maximum pulse repetition rate and the shortest pulse width were 365.5 kHz and 146 ns respectively. To the best of our knowledge, this work represented the MoS₂ firstly used as a saturable absorber (SA) in Q-switched Nd:GGG laser operating at 1.4 μm wavelength, which deepened the understanding of the Q-switched performance of MoS₂ in this spectral region.

带内泵浦下1.4μm高效MoS2基被动调Q Nd:GGG激光器

我们展示了一种在880nm LD泵浦下有效的基于MoS2的眼睛安全的被动调Q Nd:GGG激光器。最大平均输出功率约为1.05W，斜率效率约为7.0%。最大脉冲重复率和最短脉冲宽度分别为365.5kHz和146ns。据我们所知，这项工作代表了MoS2首次在1.4μm波长的调Q Nd:GGG激光器中用作可饱和吸收体（SA），这加深了对MoS2在该光谱区域的调Q性能的理解。
