Abstract: The invention relates to reflective optical elements for a dynamic deflection of a laser beam and to a manufacturing method for these reflective elements. It is the object of the invention to provide reflective optical elements for a dynamic deflection of laser beams which can be manufactured less expensively and which are flexible in their geometrical design so that they achieve improved properties in dynamic operation. In the reflective optical element in accordance with the invention, a surface of a base body and a plate-shaped reflective element are connected to one another in a planar manner and with material continuity by means of a solder connection.

Abstract: The invention relates to the hardening of the surface layer of parts of machines, plants and apparatuses and also tools. Objects for which the application is possible and advantageous are components which are subjected to severe fatigue or wear stresses and are composed of hardenable steels and have a complicated shape and whose surface has to be hardened selectively on the functional surfaces or whose functional surface has a multidimensional shape. The process for hardening the surface layer of components having a complicated shape is carried out by means of a plurality of energy input zones.

Abstract: A laser protective wall element for a housing in laser machining stations with which increased protection, in particular for the eyes of living beings, can be achieved. In a laser protective wall element for a housing at laser machining stations, an intermediate layer is present which has hot conductor properties. The intermediate layer can be formed between electrically conductive plate-like elements, an electrically conductive plate-like element and an electrically conductive coating or also two electrically conductive layers or can be arranged there. The electrically conductive plate-like elements, the coating and/or the layers are connected to an electrical voltage source as well as a measuring instrument which detects electrical current, electrical resistance and/or electrical capacity and whose measured signal change can be used for the condition monitoring of the laser protective wall element.
