Abstract

We present a single longitudinal mode Ho:YLF MOPA laser operating at 2050.7 nm by utilizing the Fabry–Perot etalon method to construct a compact SLM seed laser and employing Tm-doped fiber as the amplifier. With an output power of 336 mW generated by the seed laser, the maximum output power of 13.1 W for the single longitudinal mode MOPA laser was recorded at a pump power of 88.7 W. A peak slope efficiency of 26.9% was achieved when the pump power exceeded 58.7 W. To our knowledge, this is the first report of utilizing Tm-doped fiber to amplify the SLM operation of Ho:YLF laser.

具有SLM操作的紧凑型2.05 μm MOPA激光器

本文利用Fabry-Perot标准子方法构建了一个紧凑的SLM种子激光器，并采用掺铥光纤作为放大器，实现了工作在2050.7 nm的单纵模Ho:YLF MOPA激光器。种子激光器的输出功率为336 mW，在88.7 W的泵浦功率下，单纵模MOPA激光器的最大输出功率为13.1 W。当泵功率大于58.7 W时，峰值斜率效率达到26.9%。据我们所知，这是第一个利用掺铥光纤放大Ho:YLF激光器SLM操作的报道。
