Abstract

A procedure of operational inspection of laser technological processes has been suggested that is based on measuring spectral properties of Doppler signal of backscattering from the interaction region by optical heterodyne technique. The technique enables us to obtain the qualitative and quantitative information on hydrodynamic flows in reactor. The measurements have been performed with about 1 kW/cm² beam intensity of continuous-wave carbon- dioxide laser at the surface of a number of condensed substances by monostatic scheme of interaction.
