Abstract

An approach to CARS is described and demonstrated which permits CARS to be generated from a multiplicity of species simultaneously. The technique employs two independent broadband Stokes sources in combination with a pump laser. In addition to the two separate two-color wave-mixing processes between the pump and Stokes lasers, spectrally resolved CARS is produced in a three-color process from species whose Raman resonances correspond to the frequency differences of the two broadband sources. CARS is thus derived from a large number of species simultaneously removing the nominal limitation of CARS to interrogate only one constituent at a time.
