Device for the thermal processing of a workpiece by laser radiation, and protective hood suitable therefor

A device for the thermal processing of a workpiece with laser radiation, the device comprising:

• a) a laser processing machine, having:
• a support surface for supporting the workpiece;
• a laser processing unit with a laser processing head;
• a movement unit with a transverse gantry for moving said laser processing head relative to said support surface, said transverse gantry including a support beam that extends above said support surface, is supported laterally on said support surface, and is movable on tracks;
• b) a laser protective hood surrounding said laser processing head, said laser protective hood being open towards said support surface and being disposed for movement by said movement unit together with said laser processing head, and said laser protective hood having an outer wall, an inner wall, and a cavity formed between said outer and inner walls and having at least one laser light sensor arranged in said cavity;
• and
• c) a laser protective housing encasing said support surface, said laser processing unit, said movement unit, and said laser protective hood in form of a hood.
