Abstract: Systems and methods cut trenches of multiple widths in a material using a single pass of a laser beam. A first series of laser pulses cut a work surface of the material at a first cutting speed using a first spot size. In a transition region from a first trench width to a second trench width, a second series of laser pulses sequentially change spot sizes while gradually changing from the first cutting speed to a second cutting speed. Then, a third series of laser pulses continue to cut the work surface at the second cutting speed using a second spot size. The method provides for increased depth control in the transition region. A system uses a selectively adjustable optical component in the laser beam path to rapidly change spot size by adjusting a position of a focal plane with respect to the work surface.

Abstract: A method and system for increasing throughput of laser micromachining systems use more than one laser. Two or more pulsed laser beams are combined and then separated into multiple laser beams that enable the system to work simultaneously at multiple locations on the workpiece with pulse rates greater than those achievable with independently operating lasers while maintaining pulse energy equal to or greater than the pulse energy of each of the original independent laser beams. Most laser micromachining applications required multiple sequential pulses to process a workpiece. Increasing the pulse rate while maintaining pulse energy effects more rapid material removal and thereby increases throughput for a laser micromachining system.

Abstract: Systems and methods reduce or prevent back-reflections in a laser processing system. A laser processing system includes a laser source to generate an incident laser beam, a laser beam output to direct the incident laser beam toward a work surface, and a lens to receive the incident laser beam along a first axis of propagation that is substantially perpendicular to the work surface. The lens includes a primary axis that is substantially parallel to, and offset from, the first axis of propagation. The lens is configured to focus the incident laser beam onto the work surface along a second axis of propagation that forms a non-perpendicular angle with the work surface such that at least a substantial portion of a reflected laser beam from the work surface does not return to the laser beam output.
