摘要：
A theoretical investigation is performed of the evaporative mode of interaction between laser radiation and matter. It is demonstrated that a periodically explosive pattern of boiling is possible in dielectric liquids in the presence of free surface, if the depth of radiation absorption exceeds the size of the region of thermal diffusion. Analytical expressions are obtained for the period of bumping and for the size of surface layer destroyed by fluctuation vapor bubbles. Calculation is performed of the degree of attenuation of radiation intensity at the surface of liquid due to absorption of a part of radiation in the vapor-droplet mixture being formed.
