SYSTEM AND METHOD FOR MULTI-BEAM SCANNING

摘要

The present application relates to systems (10) and method of photoaltering a material. The system (10) includes a laser source (14) op-erable to produce a primary pulsed beam (18), a holographic optical element (32) configured to receive the primary pulsed beam (18) and transmit a plurality of secondary beams (36), and a scanner (20) operable to direct the secondary beams (36) to the material. The secondary beams (36) are based on the primary pulsed beam (18). The method includes phase shifting a pulsed laser beam to produce an input beam (36), holographically altering the input beam to produce a plurality of transmission beams (36), and scanning a portion of the material (12) with the transmission beams (36).
