Abstract

We report the first use of a Semiconductor Disk Laser (SDL) as a pump source for ~2μm-emitting Tm³⁺ (,Ho³⁺)-doped dielectric lasers. The ~1213nm GaInNAs/GaAs SDL produces >1W of CW output power, a maximum power transfer net slope efficiency of 18.5%, and a full width half maximum wavelength tuning range of ~24nm. Free-running operation of a Tm³⁺-doped tellurite glass laser under 1213nm SDL pumping generated up to 60mW output power with 22.4% slope efficiency. Wavelength tunable output is also obtained from 1845 to 2043nm. Improved performance with output powers of ~200mW and a slope efficiency of ~35% are achieved by replacing the Tm³⁺-doped glass with a Tm³⁺-doped KYW active medium. Emission of a Tm3+,Ho3+-codoped tellurite glass laser is also reported with maximum output power of ~12mW and a ~7% slope efficiency. Finally, preliminary investigations of 1213nm-pumping of a Tm³⁺,Ho³⁺-codoped silica fibre laser lead to 36mW output power with ~19.3% slope efficiency.
