Increase in efficiency of laser treatment using off-axis beams focused by mirror systems

摘要

Method of formation of space characteristics of a laser beam, based on a mathematical model of process of focusing radiation by a spherical mirror and procedure of evaluating the effect of space characteristics of a laser beam on heat state of the body radiated, has been suggested. Using this method the optimum space distribution of heat source over the material surface is attained and, as a consequence, the efficiency of a laser treatment is increased and its technological capabilities are widened.
