Abstract

Picosecond ruby laser pulses generate simultaneously Stokes pulses of the 992 cm−1 ring breathing mode and of the 3063 cm−1 CH-stretching mode of benzene in a Raman generator cell by stimulated Raman scattering under self-focusing conditions. The Raman generator light is spectrally filtered, collimated, and amplified in three Raman amplifier cells pumped by ruby laser pulses. Both first Stokes lines have been selectively amplified to short, low divergence, intense light pulses.
