Abstract:
1. A method for processing a workpiece with a laser, the method comprising: generating laser pulses at a first pulse repetition frequency; and at a second pulse repetition frequency that is lower than the first pulse repetition frequency, selectively amplifying a subset of the laser pulses, wherein selection of the laser pulses included in the subset is based on the first pulse repetition frequency and position data received from a beam positioning system, and wherein the second pulse repetition frequency is selected such that the first pulse repetition frequency is an integer multiple “n” of the second pulse repetition frequency; and offsetting an interpulse time between a first amplified pulse in the subset and a second amplified pulse in the subset by an integer multiple k of the photonic oscillator interpulse time based on a selected amount of beam delivery coordinate adjustment relative to the workpiece.
