Abstract:

The influence of surface deformations of a liquid particle on the Q-factor of resonant electromagnetic mode of the droplet is analyzed. It is demonstrated that high-order modes are more susceptible to deformation effects as compared with low-order modes. The pondermotive and thermocapillary mechanisms of droplet surface deformations are compared by their influence on the energy threshold of stimulated Raman scattering of light. It is established that the amplitude of pondermotive deformations is considerably lower than the amplitude of thermocapillary deformations; therefore, pondermotive deformations do not significantly influence the energy threshold of stimulated Raman scattering (SRS) of light.
