Abstract

A single act of boiling a liquid underheated to the saturation temperature is experimentally investigated when the liquid is exposed to continu ous-wave laser radiation introduced into the working volume by means of a thin optical fiber. It is shown that a vapor bubble formed near the end of the optical fiber during collapse forms a hot cumulative jet, the phenomenon of secondary boiling around which is observed. The secondary vapor inclusion formed around the jet has an extended shape, moves, and evolves together with it. The significant effect of this inclusion on jet-propagation dynamics is demonstrated.
