Abstract
The influence of various physical mechanisms at the stage of collapse of a vapor bubble and the subsequent formation of a cumulative jet in the process of laser-induced boiling near the end of a thin waveguide immersed in a cold liquid is studied numerically. Depending on the intensity of evaporation, three process modes are identified and described.
