Abstract

We analyze here the influence of multi-mode excitation of stimulated light scattering (SLS) in the spherical particle on the angular intensity distribution in the far-field zone. It is shown that at multi-mode excitation of SLS the scattering diagram becomes asymmetric, unlike the case, when process is realized on single resonant mode of a particle. Degree of its asymmetry significantly depends on combinations of modes excited in the particle that brings either to a significant increase of the intensity of backscattered wave, or to its weakening in the given direction. The comparison with angular intensity distribution at elastic scattering is made.
