Development of pump source for Raman amplifiers and supercontinuum generation using P-doped fibers

摘要

A high-power Raman fiber laser (RFL) with maximum output power of 4.11 W/1239 nm and 3.14 W/1484nm is obtained using a continuous wave (CW) 8.4 W/1064 mm Yb-doped double-clad fiber laser (DCFL) as a pump, phosphorous-doped fiber (PDF), and cascaded cavities made with fiber Bragg gratings (FBG). High-efficiency broadband (1434-1544nm) continuous-wave supercontinuum with average power of 2.67 W is obtained when a 350 m singlemode fiber was spliced to second stokes RFL
