摘要：
Parametric striction excitation of acoustic oscillations in droplets under intense light wave pump is considered. Threshold intensities of Mandelshtam - Brillouin scattering were calculated with account of fields inhomogeneity and resonance character of interaction. Conditions are found where threshold intensity is low and of the order of 10(3) W/m2 for water drops of radii more then 4 mum at 0.4-0.7 mum light wavelengths. The observation of the excitation is possible in spite of nonlinear detaining effects of thermal origin.
