Abstract
An efficient fibre-based Raman laser was developed on the basis of a phosph osilicate optical fibre with low optical losses, Bragg fibre gratings, cons tituting the laser cavity, were formed directly in the active fibre, The pa rameters, mathematical modelling, and optimisation of the laser were invest igated. As a result of the optimisation, the output power reached 2.4 W for pumping with radiation from a neodymium fibre-based laser with a power of 3.5 W, which corresponds to a 77% quantum efficiency of the Raman laser.
