Abstract

In this work, we fabricate the MoWS by microwave-assisted solvothermal method, and report the Q-switched Yb-doped fiber lasers (YDFL) using MoWS polymer film and tapered fiber as the saturable absorbers (SAs). The modulation depth and saturable intensity of the film SA are 5.63% and 6.82 MW cm. The shortest pulse duration and the maximum single pulse energy are 1.22 μs and 148.8 nJ for the film SA, 1.46 μs and 339 nJ for the fiber-taper SA. To the best of our knowledge, this is the first report on the Q-switched YDFL using MoWS SAs.

摘要

在本工作中，我们通过微波辅助溶剂热法制备了MoWS，并报道了使用MoWS聚合物薄膜和锥形光纤作为饱和吸收体（SA）的调Q掺镱光纤激光器（YDFL）。薄膜SA的调制深度和饱和强度分别为5.63%和6.82 MW/cm²。对于薄膜SA，最短脉冲持续时间和最大单脉冲能量分别为1.22 μs和148.8 nJ；对于锥形光纤SA，分别为1.46 μs和339 nJ。据我们所知，这是首次关于使用MoWS SA的调Q YDFL的报道。
