Successful implementation of technological processes of laser treatment is possible only if a certain spatial intensity profile is formed in a given area on the surface of the part. This is achieved by using special optical systems - beam focusators. A technological method was developed to improve the performance characteristics of parts with the adjustable spatial distribution of beam power. Distinctive features of the method areas follows: the shape of the laser spot and the distribution of the beam power density are considered as the main parameters of the treatment mode, the choice of parameters of the lasers ource and the development of technological optical systems is performed in accordance with the results of solving the inverse heat conduction problem. The permissible error of adjustment of the optical element and the required accuracy of setting the parameters of the focusable beam and the angle of rotation of the focusator are determined for use of focusators in technological processes of laser treatment of parts.
