The invention relates to a device for adjusting a beam profile of a laser beam, which is guided in a light guide of a fiber optic cable provided with a protective sleeve, wherein the device comprises a deformation device for deforming the light guide in a section of the fiber optic cable not enclosed by the protective sleeve, a housing, which is designed to surround the light guide at least in the section not enclosed by the protective sleeve, and also two holders provided at opposite ends of the housing for fixing in each case one end of a section of the protective sleeve, wherein the holders each comprise an opening for feeding the light guide to the deformation device. The invention also relates to a laser processing machine having such a device and to an associated production method.

Device for adjusting a beam profile, laser processing machine and method for producing the device

A method for laser fusion cutting of a metal workpiece including applying a laser beam to the workpiece, where a kerf is melted in the workpiece by the laser beam and a laser beam diameter in a working point is configured to expel molten material from the kerf without cutting gas.
