We present results on stimulated Raman scattering in hydrogen excited by 200-fs-duration 1-kHz repetition-rate and 0.6-W average-power Ti:sapphire (780-nm) and 0.2-W average-power second-harmonic (390-nm) laser pulses with linear and circular polarizations. Spectral and temporal measurements of the vibrational and rotational components at Stokes and anti-Stokes frequencies in the wavelength range of 289–1154 nm are reported. We observe threefold shortening of the first vibrational Stokes component pulses, excited by 400-fs-duration second-harmonic pulses.
