Significance of output:

This paper represents the first demonstration of highly efficient Raman distributed-feedback (DFB) fibre-lasers formed in short-length (30cm) optical-fibre. This result represents a world-record of 1.6W in output-power (x2 over previous record) from a fibre-DFB laser and is a major technological advance in the area. It demonstrates that lasers now can be formed in standard-fibre (10pence/metre) facilitating the formation of low-cost sources offering low-noise, narrow-linewidth, single-frequency oscillation, required for e.g. high-capacity telecommunication and gas-sensing systems. Because they utilise Raman-gain it opens up for fibre-DFB laser-operation at wavelengths where currently there are no fibre-sources available, including the important 1150-1500nm and 1640-1750nm bands.
