The threshold for stimulated Raman scattering (SRS) in CH4 gas with a 1.06µm pump has been reduced to only ~50kW using an arrangement involving synchronous pumping and confinement in a capillary waveguide. This corresponds to a threshold reduction of ~50 compared to an unguided, single pass device. This Raman laser has produced stable mode-locked 1.54µm pulses of ~12kW power and pulse duration ~100ps.
