Patent number: 4065731Abstract: A laser system which produces multiline emissions simultaneously and which is adapted for use in optical data processing systems. In particular, in a first embodiment, a unitary positive column laser comprises two sections, the first section comprising a positive column helium-cadmium laser, the second section comprising a positive column helium-neon laser, the first and second sections being in tandem. Each section may be excited separately such that optimum excitation for red laser light, produced by the helium-neon section, and blue laser light, produced by the helium-cadmium section, can be independently controlled. The present system also allows separate cadmium vapor pressure control by separately controlling the vaporization temperature of the cadmium and also allows confinement of the cadmium vapor whereby the vapor does not contaminate one of the optical windows which confines the active laser medium.Type: GrantFiled: April 27, 1976Date of Patent: December 27, 1977Assignee: Xerox CorporationInventor: Shing Chung Wang
