Abstract :
A new stable dual-wavelength fiber ring laser based on Raman amplification, deploying a dispersion-compensating fiber (DCF) as gain medium, is introduced. The gain competition effects in the fiber Raman amplification are mitigated because the two emission lines, selected by fiber Bragg grating within the resonant ring cavities, travel in opposite directions through the gain medium. The experimental results confirm that the novel multiwavelength ring laser source is stable and it offers a high optical signal-to-noise ratio.
