Abstract :
We have demonstrated a stable and tunable dual-wavelength Raman fiber laser which can be used as a pump source for hybrid type and gain controlled C- and L-band distributed Raman and lumped erbium doped fiber amplifier. A long period grating is used to suppress the gain competition between the two wavelength laser modes and prevent the high order Stokes oscillation. Intensity and wavelength tuning of the two lasing modes at 1480 nm and 1500 nm are achieved by tuning one and both of the fiber grating used in the laser cavity, respectively.
