A Compact 2.05 μm MOPA Laser With SLM Operation
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.
