Abstract:

The SRS effect in spherical transparent droplets is considered. The results are compared with the experimental data available. The angular structure of the SRS in the far zone was numerically modeled for a stationary distribution of the SRS field in a droplet. It was shown that angular distribution of Raman scattering has a maximum in the backward and forward directions with respect to the direction of incident radiation and a minimum in the direction normal to it. The SRS directional pattern is shown to be more uniform than that of the elastic scattering. This is explained by the fact that no field component at the Raman shifted frequency is diffracted on the particle contour. The angular structure of the SRS if supported by one resonance mode of a droplet is symmetric with the period multiple to π/2. At multimode regime of the SRS generation, this symmetry is not observed.
