✦ Synopsis

Resonance. enhanced coherent anti-Stokes Raman scatterin& (CARS) spectra have been obtained for the hi&Iy fluorescing aaidine dyes, acridine orange and pro&vine, iii dilute methanol solutions at submillimokir concentrations. Spectra have also been taken in the muItipIex mode by the use of a broad-band Stokes laser and a Vidicon OMA detection system. Several Raman bands are observed in the 1100-1600 crri' reggoorr originating from the aaidine ring modes. Upon decreasing the beam crossing angIe a continuous transition from the normal CARS spectrum to a negative spectrum in the nonresonant background is observed_
