Diode-pumped continuous-wave dual-wavelength c-cut Pr3+:LiYF4 laser at 696 and 719 nm 
Date: Dec 1, 2015
A continuous-wave, InGaN-LD-pumped dual-wavelength laser is demonstrated with simultaneous emission at 696 (P30→F33) and 719 nm (P30→F34) using a c-cut Pr3+:LiYF4, 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
