Abstract: A method for laser drilling holes on a moving web of material wherein the laser system can be used to drill holes having a diameter less than about 300 micron and holes having a diameter greater than about 300 micron without increasing the energy of the laser beam, and without laser profiling the hole to increase the diameter. The method comprises pulsing the laser beam a plurality of times while directing the focal point of the laser beam for each pulse on to the same target area on the material to produce a hole having an increased diameter.

Abstract: A laser cutting machine includes at least one galvo having a galvo field of view in which the galvo can cut a material moving with a speed past the galvo. A display in the machine provides an image of at least one pattern to be cut from a material, the pattern comprising of a plurality of objects with each object having a position on the material and each object comprising at least one cut. An optimizer in the machine receives the position on the material of each object of the pattern and assigns a start locations for each cut of each object and a trigger distance for each object to maximize the speed at which the material moves past the galvo while ensuring that each object is cut by the galvo at the object's respective position on the material.

Abstract: A laser beam is applied to optics to focus the laser beam into a focal point substantially on a piece of working material. An expected shift in a focal plane due to heating of the optics by the laser beam is determined. At least one feature of the optics is altered based on the expected shift so as to maintain the focal point substantially on the piece of working material.
