Abstract
Flat workpieces of brittle material be severed in a time-saving manner by an arrangement according to the invention by inducing thermomechanical stresses by laser radiation, particularly along severing lines in the same orientation in alternating directions, in that the arrangement has two coolant nozzles which selectively direct coolant to the workpiece and which, preferably coupled with optical means for shaping the laser beams, are mounted so as to be rotatable around the axis of the laser head.
