Abstract
This study investigates the stimulated Raman scattering (SRS) of mixtures. The laser-induced plasma nanoshock wave is formed by focusing an intense pulsed 532 nm laser beam on the mixtures. An enhancement at the low-frequency SRS line of the bending mode of is observed. The mechanism of enhancement was attributed to nanoshock wave resonance with the bending mode, which would preferentially excite phonon and lower energy molecular vibrations.
