N2 - This paper presents the results of an experimental study of boiling of substantially subcooled liquid initiated by its local heating through the concentrated laser radiation transmitted to the working volume via a thin optical fiber. We study in detail the evolution of a vapor-gas bubble formed near the surface of an optical fiber tip. As the bubble collapses, a liquid seal is formed, which leads to generation of a hot submerged jet directed from the fiber tip into the liquid. We attempt to explain the cumulative nature of this jet and provide estimates of its velocity that appear to be in good agreement with the experiment.
