Abstract
In a preferred embodiment, a Tm.sup.3+ :YAG laser crystal and a Ho.sup.3+ :YAG laser crystal are placed within a reflective path of a laser cavity for intracavity pumping the Ho.sup.3+ :YAG laser crystal. The Tm.sup.3+ :YAG laser crystal emits a substantially 2.0 .mu.m laser emission after being resonantly end-pumped by a pump beam at a wavelength of about 785 nm and the substantially 2.0 .mu.m laser emission is used to pump the Ho.sup.3+ :YAG laser crystal. The intracavity-pumped Ho.sup.3+ :YAG laser crystal emits an output laser emission at substantially 2.1 .mu.m. The slope efficiency of the Ho.sup.3+ :YAG laser crystal output power is about 40% of the pump power absorbed by the Tm.sup.3+ :YAG laser crystal.
