Stimulated Raman amplification of femtosecond pulses in hydrogen gas
1996
Optics Letters
Preserved Fulltext
We report efficient amplification of weak femtosecond supercontinuum pulses by a stimulated Raman scattering process in pressurized H 2 gas excited with 350-fs-duration frequency-doubled pulses from a regenerativeamplified Ti:sapphire laser. An amplification factor of 10 9 is obtained at the wavelength of 465 nm for seed pulses produced by supercontinuum generation in glass.
