N2 - This paper considers modeling of the non-stationary temperature field for the liquid near the face end of a quartz–quartz polymer fiber with a core diameter of 400 µm at the moment of the vapor bubble appearance. We present a mathemat-ical model that incorporates laws of the radiation propagation and non-stationary forms for laws of conservation of momentum, mass, and energy. We estimated the heating time and the thermal picture in the neighborhood of the fiber end required to reach the conditions for homogeneous nucleation. The results of numerical simulation are compared with the characteristics of the vapor–gas bubble, which were obtained experimentally.
