Abstract
The invention relates to a machining head () for laser machining machines, in particular for laser cutting machines, having an interface to a laser light source (), preferably to fiber-coupled or fiber-based laser sources. Said laser sources are designed for more than 500 W of average output power in the near infrared region. The interface is preferably designed for coupling an optical waveguide () for the working laser beam (). The machining head () also has a focusing optical unit () having preferably only one imaging lens. A deflecting assembly () for at least one single deflection of the working laser beam () is arranged between the interface and the focusing optical unit (). Said deflecting assembly () is designed as a passive optical element that changes the divergence of the working laser beam () in dependence on power.
