Stimulated Rayleigh wing scattering with Bessel beam pumping
R. Barillé, Suren Sogomonian, Genevieve Rivoire
We have observed SRWS without phase modulation and self focusing of the pump beam with use of a Bessel beam excitation. The experiments show at the scattering threshold two types of line spectra, and above the threshold a large band spectrum. These results are interpreted by the presence of four photon processes coupling two exciting photons, one Stokes and one anti-Stokes scattered photon, developing in cascade. This interpretation can be extended to the recent studies of soliton propagation in a planar waveguide.
