Abstract:
A laser beam delivery system comprising:a laser source for outputting a laser beam; a shaping apparatus for receiving the laser beam output by the laser and for shaping the laser beam into a plurality of separate laser beams; a converging mechanism for redirecting the plurality of separate laser beams through a clear aperture of a mirror of a repeat positioning device; the repeat positioning device redirecting the plurality of separate laser beams to an F-Theta lens; the converging mechanism being movable relative to the repeat positioning device for adjusting a degree of convergence of the plurality of separate laser beams to facilitate passage of each one of the plurality of separate laser beams pass through the clear aperture of the mirror of the repeat positioning device; and the F-Theta lens focusing the plurality of separate laser beams at an object to be processed.
