Abstract

The application of the CARS technique with the spatial separation of the exciting and probe beams allows the elimination of the background, which appears in the signal of CARS from polaritons due to four-photon processes. The propagation length 1_p of coherently excited polaritons and the ratio of direct four-photon and two-step three- photon contributions (which are determined by rho(omega)equals(chi) ⁽³)/[(chi) ⁽²)((omega) ) ]²) to the resultant CARS signal can be determined by measuring the intensity of CARS signal, as a function of spacing between the excitation and probe regions. For A₁(z) polaritons in BeO, at frequency around 372cm^-1, we obtained the following results: l_pequals(0.3_-⁺0.05)mm and (rho) approximately equals 2.5x10².
