Efficient and tunable operation of a Tm-doped fibre laser
We report on improved performance from a silica based thulium doped fibre laser. Under excitation at 810nm this system has demonstrated a near theoretical maximum slope efficiency of 36% (84% photon conversion efficiency), corresponding to 44mW of laser output power at 1900 nm for 167mW of absorbed...
