  • Method and device for detecting a focal position of a laser beam
    Patent number: 11530946
    Abstract: A method and a device for detecting a focal position of a laser beam, particularly a machining laser beam in a laser machining head, includes an optical element which is arranged in the laser beam converging toward the focal point and which is designed to outcouple a reflection from the laser beam path, and a sensor arrangement which is designed to detect beam characteristics of said laser beam in the region of the focal point in the laser extension direction, and which measures the outcoupled reflection of the laser beam at at least two locations that are offset to one another in the extension direction, in order to determine the current focal position.
    Type: Grant

  • Gas supply device and laser processing head comprising same
    Patent number: 11465237
    Abstract: A gas supply device for a laser machining head is provided for generating a homogeneous gas flow. The gas supply device includes a gas inlet, a shared volume for superimposing a laser beam and the gas flow, and a gas channel system which, starting from the gas inlet, branches at least twice and connects the gas inlet with several outlet openings at the shared volume. The gas channel system and the outlet openings are configured to provide a substantially homogeneous gas flow to the shared volume.
