Abstract

See full text

A high-speed, precise, laser-based material processing method and system are provided wherein relative movement of target material and a pulsed laser output used to process the material are synchronized. The laser-based system includes a pulsed laser source for generating a set of laser pulses, and a laser output control that controllably selects a subset of pulses from the set of laser pulses at a position beyond the laser source to obtain the pulsed laser output. The laser-based system further includes a mechanism for synchronizing the pulsed laser output with relative movement of the target material. A beam delivery and focusing subsystem delivers at least a portion of the synchronized pulsed laser output to the target material as a laser material processing output to process the target material. A positioning subsystem moves the target material relative to the pulsed laser output.
