Abstract

A continuous-wave, InGaN-LD-pumped dual-wavelength laser is demonstrated with simultaneous emission at 696 (${{}^3\mathrm{P}}_0\to {{}^3\mathrm{F}}_3$) and 719 nm (${{}^3\mathrm{P}}_0\to {{}^3\mathrm{F}}_4$) using a c-cut ${\mathrm{Pr}}^{3+}\text{:}{\mathrm{LiYF}}_4$, for the first time to our knowledge. Maximum output power of 102 mW at these two wavelengths is achieved with slope efficiency of about 15.6% with respect to the absorbed pump power. The beam propagation factors in $x$ and $y$ directions are measured to be 1.50 and 1.32, respectively.
