Abstract: Based on the Lee vaporization-condensation model, numerical solutions were obtained that describe the process of growth and collapse of bubbles formed at the end of an optical fiber during laser heating. The simulation parameters are found for which the numerical solutions correspond to the observed experimental data. Using numerical modeling, the features associated with the dynamics of the growth-collapse of a cavitation bubble and the formation of heated jets are explained

Key words: lasers, heat conduction, cavitation, evaporation, condensation.
