Abstract : In a preferred embodiment, a Tm3+:YAG laser crystal and a Ho3+:YAG laser crystal are placed within a reflective path of a laser cavity for intracavity pumping the Ho3+:YAG lasers crystal. The Tm3+:YAG laser crystal emits a substantially 2.0 micrometers laser emission after being resonantly end-pumped by a pump beam at a wavelength of about 785 nm and the substantially 2.0 micrometers laser emission is used to pump the Ho3+:YAG laser crystal. The intracavity-pumped Ho3 +:YAG laser crystal emits an output laser emission at substantially 2.1 micrometers. The slope efficiency of the Ho3+:YAG laser crystal output power is about 40% of the pump power absorbed by the Tm3+:YAG laser crystal.
