We have demonstrated Raman amplification in small core As-Se fiber. We observed over 20 dB of gain in a 1.1-meter length of fiber pumped by a nanosecond pulse of approximately 10.8 W peak power at 1.50 micrometers . The peak of the Raman gain was shifted by approximately 230 cm-1 to 1.56 micrometers . The Raman gain coefficient is estimated to be about 2.3 x 10-11 m/W, over 300 times greater than that of silica. The large Raman gain coefficient coupled with the large IR transparency window of these fibers shows promise for development of As-Se Raman fiber lasers and amplifiers in the near, mid and long IR spectral regions.
