Paper Abstract

We report tunable thulium/holmium-doped single mode fiber laser passively Q-switched by an antimonide-based semiconductor saturable absorber mirror (SESAM) and boosted in Tm/Ho amplifier up to 2 W of average power. Pulse operation tunable from 1960 nm to 1990 nm with pulse energies up to 30 μJ has been achieved. The study presents the first demonstration of 2 μm Q-switched fiber laser using antimonide semiconductor technology.
