Patent ID: 7106436

Claim:
A triple-pump coherent anti-Stokes Raman scattering system for simultaneous measurements of temperature and species concentrations with high spatial and temporal resolution in a gaseous system, comprising: (a) first and second pump lasers and first and second narrowband dye lasers for generating output beams near two substantially distinct wavelengths; (b) a broadband dye laser; (c) optical means for directing the output beam from said first pump laser onto said first narrowband dye laser and onto said broadband dye laser and for directing the output beam from said second pump laser onto said second narrowband dye laser; (d) optical means defining a probe region for receiving a gaseous sample and for directing the output beams from said first pump laser, said first and second narrowband dye lasers and said broadband dye laser through said probe region; and (e) detector means for detecting the optical output from said probe region.
