Abstract

A diode-pumped simultaneous continuous-wave (cw) dual-wavelength Pr3+:LiYF4 laser in the green spectral region is experimentally demonstrated. We calculate the condition of gain-to-loss balance via an uncoated glass plane to achieve the simultaneous dual-wavelength operation. The simultaneous dual-wavelength Pr3+:LiYF4 laser at 546nm in π-polarization and 550nm in σ-polarization is experimentally realized. At an absorbed pump power of 1.5W, the maximum output power obtained at 546nm and 550nm is 184mW and 158mW, respectively.
