INRICHTING VOOR HET AUTOMATISCH BEWERKEN VAN WERKSTUKKEN DOOR MIDDEL VAN LASERSTRALEN.

摘要

Workpieces are fed in succession to a laser beam to be machined thereby, the laser beam being produced by a laser resonator oscillating in the fundamental transverse mode and incorporating a laser head with a laser rod and energizing lamp, and two spaced mirrors flanking the head and aligned therewith. The mirrors are spaced at a distance to provide an effective mirror spacing which is equal to one half of the focal length of the laser rod, the rod acting as a condenser lens at operational temperatures.
