Paper Abstract

There is investigated the hydrodynamical flow of the glass at its surface acted by the laser scanning beam. Alterations of the glass viscosity and surface tension by local surface heating are taken into account. Stationary flow regime conditions, by which the crest of the softening material follows the irradiated zone with the same velocity and glass surface becomes smooth, are defined. The cases of the point and extended sources are considered.
