Abstract:

In this paper we consider how the multimode excitation of stimulated Raman scattering in a spherical particle influences the angular distribution of radiation intensity in the far zone. It is shown that at multimode excitation of the SRS the directional pattern becomes asymmetric in contrast to the case when a single resonance mode of the particle participates in this process. The degree of asymmetry significantly depends on the combination of modes excited in the particle. This causes either a significant increase in the intensity of the wave scattered in the backward direction or its weakening in this direction. The results are compared with those for the case of elastic scattering.
