Resonant four-wave mixing spectroscopy of transient molecules in free jets

We apply two different resonant four-wave mixing techniques to transient molecules that are produced by laser vaporization into a supersonic expansion. Degenerate four-wave mixing (DFWM) excitation spectra are obtained for C3 and SiC2 and two-color laser-induced grating spectroscopy (LIGS) is used t...

Description
Summary:We apply two different resonant four-wave mixing techniques to transient molecules that are produced by laser vaporization into a supersonic expansion. Degenerate four-wave mixing (DFWM) excitation spectra are obtained for C3 and SiC2 and two-color laser-induced grating spectroscopy (LIGS) is used to produce background-free stimulated-emission-pumping spectra of SiC2.
