Optical cavitation of transparent liquids exposed to broad-band laser light
Bunkin N. F. , Karpov V. B.
A new cavitation regime has been observed as laser light with a wide frequency spectrum Δω interacts with a transparent liquid. The effect is shown to arise under the condition Δω >( ν/с) ω0 = ft (ω0 is the central frequency of the spectrum, с is the velocity of light, and ν is the hypersound velocity in the liquid). A theoretical model is proposed on the basis of a new representation of a liquid: as a colloid of metastable clusters of ultramicroscopic gas bubbles.
