  • Publication number: 20240001484
    Abstract: A method includes receiving, during a period of time, a continuous wave laser beam at an acousto-optic deflector (AOD) having a first AOD and a second AOD. A plurality of laser pulses is generated from the received beam using the first acousto-optic deflector (AOD) to the laser beam along a first axis and using the second AOD to deflect the laser beam deflected by the first AOD along a second axis.

  • Patent number: 11738405
    Abstract: A laser processing system for micromachining a workpiece includes a laser source to generate laser pulses for processing a feature in a workpiece, a galvanometer-driven (galvo) subsystem to impart a first relative movement of a laser beam spot position along a processing trajectory with respect to the surface of the workpiece, and an acousto-optic deflector (AOD) subsystem to effectively widen a laser beam spot along a direction perpendicular to the processing trajectory. The AOD subsystem may include a combination of AODs and electro-optic deflectors. The AOD subsystem may vary an intensity profile of laser pulses as a function of deflection position along a dither direction to selectively shape the feature in the dither direction. The shaping may be used to intersect features on the workpiece. The AOD subsystem may also provide rastering, galvo error position correction, power modulation, and/or through-the-lens viewing of and alignment to the workpiece.
