Abstract

We have demonstrated a room-temperature laser on the ${{}^6\mathrm{H}}_{13/2}$–${{}^6\mathrm{H}}_{15/2}$ transition of ${\mathrm{Dy}}^{3+}$ in Dy:BaYb₂ F₈ at 3.40 $\mathit{\mu }\mathrm{m}$. A pulsed $1.3-\mathit{\mu }\mathrm{m}$ Nd:YAG laser was used as the pump. Our measured spontaneous-emission spectrum for the ${{}^6\mathrm{H}}_{13/2}$–${{}^6\mathrm{H}}_{15/2}$ band indicates that this laser should be continuously tunable between 3.0 and 3.4 $\mathit{\mu }\mathrm{m}$.
