Abstract

We present a high-power, semi-random Raman fiber laser (SRRFL) where the Stokes wavelengths are determined by discrete fiber Bragg gratings. Utilizing this configuration with Raman fiber, we achieved powers of 264, 181 and 154 Watts at 1480, 1690 and 1824 nm respectively, while with a standard coupler fiber we achieved 366, 265, 247 and 234 Watts at 1174, 1240, 1310 and 1390 nm respectively. The overall peak efficiency was greater than in a standard resonator despite a far simpler configuration and only slightly below the maximum reported for a cascaded Raman amplifier.
