Abstract
A method is proposed for on-line monitoring of laser industrial proces sing. The method is based on optical heterodyne measurements of the Do ppler backscattering signal generated in the interaction zone. Qualita tive and quantitative information on hydrodynamic flows in the interac tion zone can be obtained. A report is given of measurements, carried out at cw CO2 laser radiation intensities up to 1 kW/cm(2), on the sur faces of a number of condensed materials irradiated in the monostatic interaction configuration.
