Abstract
The apparatus comprises a laser radiation generator which directs a laser beam onto a workpiece to be treated, and a reflector capable of re-directing onto the workpiece undergoing treatment the radiation reflected and/or scattered by the piece. The reflector is formed in such a way as to cause the radiation reflected and scattered by the piece to be re-focused in a zone that is different from but adjacent the zone struck directly by the radiation emitted by the laser generator. In this way a pre-heating or a post-heating of the zone of the workpiece struck directly by the radiation emitted by the generator may be effected.
