Abstract :
A flexibly-tunable multi-wavelength Raman fibre laser based on the polarisation maintaining fibre (PMF) Lyot-Sagnac filter after composing fibre Bragg grating cavity is demonstrated experimentally. The number of channels and wavelength spacing of the Raman laser can be controlled readily by /spl Delta/n /spl middot/ L products of PMF segments in the intracavity PMF Lyot-Sagnac filter.
