Abstract : The present invention is a fluorozirconate laser host doped with a sufficient amount of Tm(3+) 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 Tm(3+) ions from the (3)H6 ground state to the (3)F4 excited state and then from the (3)F4 excited state to the (3)H4 excited state.
