Three-laser coherent anti-Stokes Raman scattering measurements of two species.
A three-laser, coherent anti-Stokes Raman scattering (CARS) technique for the simultaneous acquisition of spectra from two species has been developed. A narrow-band, tunable dye-laser beam is used as one of the CARS pump beams. The frequency spacing between the spectra of the two species can be adjusted by changing the frequency of the dye-laser pump beam, enabling the spectra to be displayed at high resolution (0.5 cm(-1)) on the same intensified diode array detector.
