Abstract

We demonstrated a simultaneous CW depolarized multiwavelength Raman fiber ring laser with 58 channels within 3 dB bandwidth and 50 GHz channel spacing at room temperature using fiber Fabry-Perot tunable filter (FFP-TF), 16 km dispersion-compensating fiber (DCF) and Raman pump laser diodes at 1428.2, 1445.8 and 1463.4 nm wavelengths. The output DOP was about 2.2%. By changing pump power ratio for the three wavelengths, different operating ranges could be obtained. if cavity design is optimized, more output power can be easily achieved. By selecting different pump wavelengths, different range of operation will be possible.
