A continuous-wave, InGaN-LD-pumped dual-wavelength laser is demonstrated with simultaneous emission at 696 (P-3(0) (F-3(3)) over right arrow) and 719 nm (P-3(0) (F-3(4)) over right arrow) using a c-cut Pr3+:LiYF4, for the first time to our knowledge. Maximum output power of 102mWat 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. (C) 2015 Optical Society of America
