Low threshold operation of a waveguide CH<sub>4</sub> Raman laser at 1.54µm

By D.P. Shepherd, D.C. Hanna, S.G. Mussett and M.T.T. Pacheco


A convenient source of high-power (~20 kW) stable mode-locked pulses at 1.54 µm, suitable for pulse-compression studies in the negative group-velocity-dispersion region of optical fibres, is described. The source is based on a capillary-waveguide Raman laser, using CH<sub>4</sub> gas, and pumped by a mode-locked Q-switched CW Nd:YAG laser. Initial results for a synchronously pumped Raman laser are also presented
