Abstract

We present results on stimulated Raman scattering in H₂, D₂, HD and CH₄ 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 circular polarization. Spectral and temporal measurements of the vibrational and rotational components at Stokes- and anti-Stokes frequencies in the wavelength range 289 - 1154 nm are reported. We observed 2.5 times shortening of the vibrational Stokes component pulses in H₂ and D₂ exited by 350 fs-duration second harmonic pulses.
