FIELD: physics.
SUBSTANCE: proposed method comprises, apart from surface heating of material along its outline by elliptical laser beam oriented along tangential line to outline points, a volume heating by laser beam. Note here that laser beam center is shifted radially from the processing outline center, while preliminary cut on material surface is made radially with respect to processing outline.
EFFECT: ruling out shift of micro fracture being made from processing outline.
