Over the past years mid-infrared lasers have attracted considerable technological and scientific interests. 2 um sources can be used in various applications such as: remote sensing [1], free space communication [2], LIDAR [3], material processing of polymers [4], medicine and surgery [5], or pump sources for mid-IR OPA [6].
In this paper we present development of 2 p,m fiber front-end for Ho: YAG thin disk amplifier with average power >10 W. The front-end consists of passively mode-locked soliton holmium fiber ring oscillator followed by thulium/holmium-fiber tandem amplifier. Self-starting holmium fiber oscillator work in soliton operation at 23 MHz repetition rate, 15 mW of output average power and 1 ps output pulse duration.
Progress and current status of 2 p,m laser system (PERLA D) at HiLASE centre will be presented.
