Abstract

We present the results on stimulated Raman scattering in hydrogen excited by 200 fs-duration 1 kHz repetition rate and 0.6 mW average power Ti:sapphire laser (780 nm) and 0.2 W average power second harmonic (390 nm) pulses with linear and circuit polarization. We report on the spectral and temporal measurements of the various generated vibrational and rotational components at Stokes- and anti-Stokes frequencies in the wavelength range 289 - 1154 nm. At optimal conditions at 390 nm pump wavelength the SRS signal of 30 mW average power was obtained at the first (465 nm) and the second (577 nm) vibrational Stokes. The shortest measured duration of the vibrational Stokes components was by 3 times less than the duration of the pump pulses.
