Study of growth and subsequent collapse of a vapor bubble formed as a result of exposure of laser radiation on an underheated liquid
The object of an experimental study is a vapor bubble formed in a subcooled liquid due to absorption of laser radiation transmitted into the working volume through a thin optical fiber. Evolution of a bubble is characterized by its rapid growth and collapse with the generation of a hot submerged jet. Some features of the process under study are considered in relation to the field of medicine. Normal saline is used as the working fluid. It is shown that under the same conditions (radiation power, optical fiber diameter, and initial temperature of liquid), the dimensions reached by a vapor bubble in saline are much smaller than those in pure water. A significant influence of the shape of a fiber tip on the nature of the process under study was revealed. © 2023, A.A. Chernov, A.A. Levin, and T.P. Adamova.
