Krylov V, Rebane A, Erni D, Ollikainen O, Wild U, Bespalov V, Staselko D. Stimulated Raman amplification of femtosecond pulses in hydrogen gas. Opt Lett. 1996;21(24):2005-7.
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.
