A system which utilizes a source of ultraviolet radiation to mark a surface or to cure selectively a photosensitive paint applied to a surface. The source of UV light is either a laser or a broadband source and the light is controlled by an aperture and/or a stencil apparatus. The photosensitive paint is applied by a controlled technique as a protective or a decorative coating.

Technique for the application and cure of photosensitive paints

The discrete ballast resistors associated with the multiple pin array of laser cathode structures are replaced by a bulk resistive material in the form of an integral bar or slab which is maintained in contact with the plurality of pin electrodes comprising the laser cathode assembly to provide a stable ballast means. The bulk resistive member employed to provide the ballast for the pin electrodes can exhibit non-linear resistive characteristics to provide greater laser discharge stability with less power dissipation.
