Experimental Evaluation of a Fibre Raman Oscillator Having Fibre Grating Reflectors

Abstract
We report on the construction and characterization of a novel fibre Raman oscillator which used fibre grating reflectors rather than discrete mirrors to form the Raman resonator. This was synchronously pumped by a c.w. mode-locked Nd : YAG laser operating at 1·06 µm. Spectral and temporal characteristics of such oscillators formed by two gratings and by one grating and a conventional mirror are presented.
