Abstract
A solid workpiece, e.g. a glass tube, is shaped by a focussed beam of visible light or light in an adjacent portion of the electromagnetic spectrum in a material removal, cutting or drilling operation and is heat-treated or remelted or shaped in a plastic state by heating that second beam which is less focussed or even divergent. The beams derive from a common source, a CO.sub.2 laser, and pass through a splitting deflecting system so that the beams can be directed simultaneously either parallel to one another or with an inclination to one another at the same or different regions of the workpiece which is held in a holder capable of both rotating the workpiece and translating same.
