Study of the longitudinal distribution of power generated in a random distributed feedback Raman fibre laser with unidirectional pumping (Conference Paper)

摘要

The longitudinal distribution of the Stokes-component power in a Raman fibre laser with a random distributed feedback and unidirectional pumping is measured. The fibre parameters (linear loss and Rayleigh backscattering coefficient) are calculated based on the distributions obtained. A numerical model is developed to describe the lasing power distribution. The simulation results are in good agreement with the experimental data.
