Abstract

Room-temperature, all-solid-state, broadly tunable laser operation of ${\mathrm{Cr}}^{2+}$-doped CdSe has been demonstrated. Pumping with a $Q$-switched Tm, Ho:YLF laser running at a 1-kHz repetition rate achieved broadband output of 500 mW at $2.6 \mathit{\mu }\mathrm{m}$ with 48% absorbed power slope efficiency. With reduced efficiency, as much as 815 mW of power was obtained. With a diffraction grating, the ${\mathrm{Cr}}^{2+}:\mathrm{CdSe}$ laser was tuned from 2.3 to $2.9 \mathit{\mu }\mathrm{m}$ with 10-nm bandwidth (FWHM) and output power up to 350 mW.
