Zusammenfassung:	A visible light alignment system mounted on a line narrowing module of a UV laser. The system includes an alignment platform on which a small visible light laser is mounted and beam directing optics to direct the visible light beam to reflect off an illumination surface of a first prism in a prism beam expander at an angle such that the visible light beam proceeds collinearly with the UV laser output beam.
