ABSTRACT:
An apparatus and process for generating precision ink jet nozzle arrays in substrates is disclosed. The apparatus includes laser output through an alignment path, power monitor, expansion telescope and scanner. Preferably, beam division optics are used in conjunction with the scanner to divide out a plurality of beams and scan simultaneously a corresponding plurality of computer generated holograms (CGHs). These computer generated holograms are configured and scanned so that the generated image--preferably in the first order of diffraction--produces at least a row of ink jet holes having precision dimension and alignment preferably without optical interference from other diffraction orders. Utilizing the disclosed process and apparatus, a one step system is disclosed for going from a substrate to a finished nozzle array suitable for use with ink jet printers.
