Abstract

A high-power Raman fiber laser (RFL) with maximum output power of 4.11 W/1239 nm and 2.24 W/1484 nm is obtained using a continuous wave (CW) 8.4 W/1064 nm Yb-doped double-clad fiber laser (DCFL) as a pump, phosphorous-doped fiber (PDF) and cascaded cavities made with fiber Bragg Gratings (FBG). RFL performance for the 300, 700 and 1150 m PDF lengths and output mirror reflectance was experimentally investigated by observing maximum output power, slope efficiency, threshold power, and full-width at half maximum at both the first and second Stokes wavelength.
