Abstract

The threshold for stimulated Raman scattering (SRS) in CH4 gas with a 1.06 μm pump has been reduced to only ~50 kW 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 1.54 μm pulses of ~12 kW power and pulse duration ~100 ps.
