ABSTRACT:
A laser processing method irradiates an excimer laser beam at a surface of an object composed of a polymer material that absorbs the excimer laser beam. The polymeric object is substantially free of lubricants that reflect wavelengths within the range of operation of the excimer laser beam. The invention also relates to a nozzle plate of an ink jet device, which does not contain such lubricants, produced with an excimer laser beam.
