FIELD: radio engineering.
SUBSTANCE: method is implemented in the following way. Owing to selection of curvature radii of completely reflecting and output resonator mirrors and distances between resonator mirrors, laser emission beam parameters are adjusted by setting the specified ratio between width of resonator stability zone and focal power value of thermal lens, which is induced in active element by pumping radiation. Then, laser emission beam is focused on the processed material. When it is necessary to change the material processing mode, pumping power is changed at maintaining the specified ratio between width of resonator stability zone and focal power value of thermal lens. In order to maintain the specified value of the ratio, curvature radius of completely reflecting mirror is changed and it is installed at the specified distance from active element.
EFFECT: improvement of operating characteristics of laser processing of materials with various properties.
