2.05 μm high-energy thulium-doped fibre amplifier based on backward pumping

Abstract We demonstrate a thulium (Tm)-doped fibre amplifier using a Ho: GdVO4 solid-state laser as the master oscillator operating at 2048.53 nm. In experiment, a novel spatial coupling system was used, combining a single lens with a curved end cap to simplify the structure and reduce losses. The i...
