The present invention is a fluorozirconate laser host doped with a sufficient amount of Tm3 ions to permit significant emission at a wavelength between about 790 nm and about 830 nm when pumped at a wavelength or wavelengths to excite Tm3 ions from the 3H6 ground state to the 3F4 excited state and then from the 3F4 excited state to the 3H4 excited state.
