Narrow-band generation and mode correlations in a short Raman fibre laser

We design a Raman fibre laser with a short cavity providing narrow-band generation. The laser is based on a commercial single-mode fibre (980-HP) span of 12 m length. The laser generates up to 11 W of intracavity power. Even at high generation power, the laser spectrum is narrow (less than 200 pm)-s...

Description
Summary:We design a Raman fibre laser with a short cavity providing narrow-band generation. The laser is based on a commercial single-mode fibre (980-HP) span of 12 m length. The laser generates up to 11 W of intracavity power. Even at high generation power, the laser spectrum is narrow (less than 200 pm)-several times narrower than for conventional Raman fibre lasers based on longer fibres. The intensity dynamics reveals indications of mode correlations.
