Patent ID: 7238913

Claim:
A flexibly optimized material processing system comprising: a laser emitter configured to emit a laser beam; beam adjusting optics having an adjustable beam expansion ratio, and configured to adjust the emitted laser beam by adjusting the beam expansion ratio; beam directing optics configured to provide a variable effective pupil corresponding to the adjusted laser beam, the beam directing optics further configured to direct the adjusted beam to one or more targets within a scan field corresponding to at least one selected area of a substrate; a lens, having a field of view encompassing at least the scan field, configured to focus the directed laser beam onto the one or more targets within the scan field; and a control processor configured to receive input corresponding to a material processing parameter and to issue at least one optimized control signal corresponding to the input to reduce degradation over the field of view based on the at least one material processing parameter wherein one said optimized control signal is an optimum scan field value corresponding to one of the group of values consisting of the effective pupil size of the beam directing optics, a focused laser beam spot size, a positional accuracy, a scanning speed, a material handling step size of a motion system, and a telecentricity value.
