Abstract:
1. Method of manufacturing a laser array having a plurality of lasers, comprising the steps of: providing a transparent substrate having a plurality of openings, each one of said plurality of openings passing at least partially through a first surface of said transparent substrate, said transparent substrate having a second surface opposite said first surface, and each of said plurality of openings being configured to support one laser of said plurality of lasers of said laser array; arranging each one of said plurality of lasers into an associated one of said plurality of openings for directing light toward said second surface; forming at least two optical features on said first surface of said transparent substrate adjacent said laser array; altering at least a portion of said second surface of said transparent substrate; and altering at least a portion of said second surface of said transparent substrate; and, directing a collimated beam of light through said at least two optical features and onto said at least portion of said second surface, said at least two optical features focusing said collimated beam of light onto said at least a portion of said second surface to form precisely located at least two fiducial marks thereon.
