摘要： The present disclosure relates generally to a mounting structure for a movable lens in a laser processing system for preventing vibration during movement of the lens. The present disclosure provides a system for moving an optical element comprising a frame, at least one optical element, and a drive for moving the at least one optical element, where the at least one optical element and the drive are connected to the frame via first and second spring members, respectively.

摘要： 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.

摘要： 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.
