Fluid analysis by laser-induced gratings in the mid- and near-infrared

The presentation will introduce the nonlinear optical method laser-induced grating scattering (LIGS) spectroscopy, which is capable of determining multiple physicochemical and thermodynamic parameters simultaneously. The focus will be on LIGS experiments employing excitation radiation in the mid- and near-infrared spectral range enabling vibrational spectroscopy. Example applications of LIGS to a variety of fluid systems including ionic liquids, gas mixtures, and flames are presented to highlight the potential and versatility of the method.
