Abstract: A laser processing head for a laser beam uses actuators engaged with a delivery fiber end to deflect the fiber end relative to an optical axis. The laser beam from the fiber end is collimated by a collimator and is then focused by a focusing lens disposed in the head beyond the collimator to a focal point. The focal point of the laser beam is deflected from the optical axis in relation to the deflection of the fiber end. The fiber end and the actuators are housed in a sealed module. Deflection of the laser beam can be sensed by reflecting portion of the laser beam to a sensing element so a control system can monitor and control the fiber end's movement.

According to the present disclosure a detailed determination of properties of a high-power laser beam takes place in the direction of an optical fiber or laser beam entering a laser processing head connected to the laser source and these measurements can be performed during the processing operation. The device according to the present disclosure has optical sensors for measuring the intensity and respective current laser power.

Abstract: A laser processing head for a laser beam uses actuators engaged with a delivery fiber end to deflect the fiber end relative to an optical axis. The laser beam from the fiber end is collimated by a collimator and is then focused by a focusing component disposed in the head beyond the collimator to a focal point. The focal point of the laser beam is deflected from the optical axis in relation to the deflection of the fiber end. The fiber end and the actuators are housed in a sealed module. Deflection of the laser beam can be sensed by reflecting portion of the laser beam to a sensing element so a control system can monitor and control the fiber end's movement. A mode-stripper in the sealed module removes light from cladding of the delivery fiber, and an actively cooled absorber in the module around the fiber absorbs the energy.

Abstract: In one example, system includes a source for providing a laser beam and a collimator including a plurality of lenses positioned along a beam path of the laser beam. At least one lens of the plurality of the lenses is transversely movable relative to the laser beam path to induce angular movement or deflection of the laser beam. The collimator is positioned in the beam path and is structured such that the laser beam at the at least one lens has a reduced diameter relative to the diameter of the laser beam exiting the collimator. The systems disclosed herein may be used in connection with systems for laser cutting a component, laser machining a component, or laser welding or otherwise joining two or more components with a laser, amongst other variations.

Abstract: The disclosure relates to a system and a method for monitoring the state of optical elements of a device for laser material processing. According to the present disclosure a detailed monitoring of the state of optical elements of a device for laser material processing takes place by monitoring properties of laser radiation in the direction of an optical fiber or laser radiation entering a laser processing head connected to the laser source and these measurements, which can be performed during the processing process. The device according to the present disclosure has optical sensors for measuring the intensity and respective current laser power.

Abstract: A laser processing head for directing a laser beam includes two reflectors and a sole lens element. The first reflector disposed in a housing's interior reflects the laser beam from a source to the second reflector, which then reflects the laser beam toward a process zone for a workpiece. The single lens element is disposed in the housing's interior between the reflectors. The lens element can be moved to adjust a focal position of the laser beam beyond the housing's outlet. To reduce contamination, one or more nozzles are configured to direct purge gas across one or more of the first reflector, the second reflector, and the lens element, while one or more collection areas disposed in the interior are configured to collect contamination directed from the purge gas.

Abstract: A motor vehicle has a surroundings lighting device, where the surroundings lighting device includes a first projection module arranged adjacent to a pivotable vehicle door of the motor vehicle in an immobile vehicle bodywork component, where when the first projection module is switched on, the first projection module projects a light distribution onto the ground adjacent to the immobile vehicle bodywork component. A second projection module is arranged on the outside of the vehicle door, where when the second projection module is switched on, the second projection module projects a pictogram onto the ground. The surroundings lighting device is configured to, when an event which is triggered by a user in the surroundings of the motor vehicle is detected, switch on the first projection module and at the same time, or after a delay, switch on the second projection module such that the pictogram is projected onto the light distribution.
