Abstract

We discuss what we believe is the first continuous-wave mode-locked Ho:YAG ceramic laser. We produced a mode-locked pulse using an acousto-optic modulator. We used a 1.91 μm Tm-fiber laser as the pump source. At the incident pump power of 11.4 W, we achieved the maximum output power of 1.84 W at 2122.1 nm in a continuous-wave mode-locked regime. We obtained a short-duration pulse of 241.5 ps at a repetition frequency of 82.15 MHz and achieved the beam quality factor M2 of 1.2. In addition, the maximum single pulse energy was 22.4 nJ.
