Simultaneous two-color CW Raman fiber laser with maximum output power of 1.05 W/1239 nm and 0.95 W/1484 nm using phosphosilicate fiber

High-power two-color CW Raman fiber laser is obtained with simultaneous outputs at 1239 nm and 1484 nm which uses CW 8.3 W Yb-doped double-clad fiber laser at 1064 nm as a pump, phosphosilicate fiber, and cascaded cavities consisting of two pairs of fiber Bragg grating mirrors. Maximum output powers are 1.05 W at 1239 nm and 0.95 W at 1484 nm with 700 m of phosphosilicate fiber. The output characteristics of this laser for different fiber lengths are reported.
