Abstract
We investigate the concentration dependence of the femtosecond coherent anti-stokes Raman scattering (CARS) signals collected from several mixtures of molecules. We demonstrate a clear quadratic dependence of the transmitted CARS signal on the number of molecules of pyridine in water by looking at the Raman signal at 1030 cm-1. Using a backscattering configuration we study the quadratic concentration dependence in solid mixtures of dipicolinic acid, calcite, and gypsum in powder form.
