Abstract
The paper is devoted to the problem of derivation of optimum conditions for the development of stimulated light scattering (SLS) processes in spherical micron-sized particles. The equation for threshold pumping intensity in the case of realization in a particle the conditions of a double SLS resonance for incident and scattered waves was obtained. The coefficient of spatial field overlapping Bc((omega) L, (omega) S) was introduced. The coefficient Bc((omega) L, (omega) S) is shown to be approximately one order of magnitude higher when the mode order of input and output resonances are equal, then when they are different. The main factor determining the value of Bc((omega) L, (omega) S) is the FWHM of excited modes.
