ABSTRACT:
A semiconductor laser device that is modular can readily be changed to produce laser configurations for a broad spectrum of applications, using a minimum of components. A set of semiconductor modules covering wavelengths and polarizations of interest in specific technologies can be coupled to one of two beam shaping modules and projected through a selected objective optics module to provide large and small circular beams as well as broad and narrow line segments. Resolution enhancing and diffraction limiting filters may be included in the objective optics.
