| Summary:
We report a study of soliton self-frequency shifting in hydrogen-filled
hollow-core fiber. The combination of hydrogen and short 40-fs input pulses
underlies clean and efficient generation of Raman solitons between 1080 and
1600 nm. With 240-nJ input pulses, the Raman soliton energy ranges from 110 to
20 nJ over that wavelength range, and the pulse duration is approximately 45
fs. In particular, 70-nJ and 42-fs pulses are generated at 1300 nm. Numerical
simulations agree reasonably well with experiments and predict that
microjoule-energy tunable pulses should be possible with higher-energy input
pulses.
