Laser beam delivery system with trepanning module
First Claim
1. 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.

Abstract
A laser beam delivery system for supplying a laser beam to a computer generated hologram which shapes and divides the supplied laser beam into a plurality of pseudo flat top laser beams. The plurality of pseudo flat top laser beams are then passed through collimated optics which alter the beams so that the beams are conveyed along the optical axis in a parallel manner. The plurality of collimated laser beams then passes through a converging mechanism which facilitates converging of the plurality of separated collimated laser beams through a clear aperture of a mirror of a first repeat positioning device so that all of the light is received by the repeat positioning device and appropriately reflected thereby to a second mirror of a second repeat positioning device and then to a rear surface of an F-Theta lens. The F-Theta lens focuses the plurality of separated collimated laser beams at the object to be processed. The converging mechanism facilitates converging of all of the supplied light so that substantially all of the supplied light passes through the clear aperture(s) of the repeat positioning device(s).
