AI Article Synopsis
- The study focuses on soliton self-frequency shifting in a hydrogen-filled hollow-core fiber, utilizing short 40-fs input pulses for effective Raman soliton generation.
- Raman solitons were generated with wavelengths ranging from 1080 to 1600 nm, showing energy levels from 110 to 20 nJ based on 240-nJ input pulses, with notable results at 1300 nm.
- Numerical simulations support experimental findings and suggest that using higher-energy input pulses could lead to tunable microjoule-energy pulses.
Article Abstract
We report a study of soliton self-frequency shifting in a 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.
