Abstract

We demonstrate a diode end-pumped Yb, Er, Ho:Gd1.17Y1.83Sc2Ga3O12 (GYSGG) laser operated at 2.79 μm in continuous-wave mode. Spectral analysis shows that Yb3+ and Ho3+ act as sensitizer and deactivator ions, respectively. Pumping with a 967 nm laser diode produces the maximum output power of 411 mW, corresponding to optical–optical conversion and slope efficiencies of 11.6% and 13.1%, respectively. The minimum laser threshold is only 81 mW because of Ho3+ doping. The laser properties are only slightly influenced by 100 mrad gamma irradiation. The Yb, Er, Ho:GYSGG crystal possesses excellent radiation resistance and is a potential laser gain medium in radiant environments.
