Dynamics of a vapor bubble induced by laser heating of water in a capillary

The results of an experimental study of the evolution of a laser-induced vapor bubble in a subcooled liquid under spatially constrained conditions (in a capillary) are presented. The influence of geometric parameters on the nature of the process is studied. It was revealed under what conditions the collapse of the bubble is accompanied by the generation of a submerged jet directed from the end of the fiber into the depth of the liquid, and when this does not occur. It is shown that in the latter case, a standing pressure wave is presumably formed in the liquid.
