331 945G

A laser device for generating multiline emissions when appropriately energized. The device consists of two major components, an anode-cathode assembly and, in a first embodiment, an adjustable brewster end section or in a second embodiment, an integral mirror end section. The anode-cathode assembly comprises one center located short cylindrical anode and two segmented cylindrical hollow cathodes located symmetrically on each side of the anode, the inner diameter of the hollow cathodes being variable depending on the particular laser transition involved and particular output level required, the length of each cathode also being variable to adjust the gain of the selected laser transition. The anode and cathode are electrically insulated by a cylindrical metal ceramic seal. The outer surface of the cathode is covered with quartz insulating sleeves to prevent electrical discharge from the outer cathode surface and to encourage effective inner cathode discharge.

An integral mirror type laser system which produces miltiline 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 coaxially aligned and having different inner diameters. Simultaneous excitation in the two different sections provides optimum excitation for red laser light, produced by the helium-neon section and blue laser light produced by the helium-neon-cadmium section. 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. By proper selection of the optical cavity parameters, simultaneous red and blue laser oscillations can be obtained for application in any optical data processing system that requires a red and blue laser radiation source. In a second embodiment, the helium-cadmium section is replaced by with a helium-selenium section whereby the tandem laser system is capable of producing multiline laser radiation in the red, blue and green colors.

The anode-cathode assembly comprises one center located short cylindrical anode and two segmented cylindrical hollow cathodes located symmetrically on each side of the anode. The anode and cathode are electrically insulated by a cylindrical metal ceramic seal. The outer surface of the cathode is covered with quartz insulating sleeves to prevent electrical discharge from the outer cathode surface and to encourage effective inner cathode discharge. The cathode is thermally connected to the external environment through a structure coupled to the cathode and the laser tube envelope thus allowing heat generated within the cathode due to the electrical discharge to be effectively conducted away thereby allowing higher input power load into the cathode for selected lasing action which requires a relatively high excitation input. A metal vapor reservoir may be provided and is preferably attached to the anode section for metal vapor laser operation.

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. By proper selection of the optical cavity parameters, simultaneous red and blue laser oscillations can be obtained for application in any optical data processing system that requires a red and blue laser radiation source.

A laser structure for generating white laser light when energized by a source of dc voltage. The laser tube structure comprises a gas-filled envelope having a longitudinal axis, an anode electrode forming a portion of the envelope. A hollow cathode is positioned within the envelope and coaxially disposed with respect to the anode electrode portion of the envelope. Members are coaxially aligned with the ends of the envelope such that a structure is provided for confining a gaseous medium therein, a dc voltage applied between the cathode and anode electrode creating a discharge therebetween, the discharge stimulating continuous wave laser emission along the longitudinal axis of the cathode, the laser emission comprising simultaneous multi-line emissions in the form of white light.

A radiation emission device characterized by a cylindrical cathode enclosed by an elongated envelope having two end sections is disclosed. A pair of anodes, one of which is located along each end section, serves to provide electrical energy to excite material inside the envelope, and to further provide a cataphoretic effect to prevent the excited material from drifting into contact with radiation transmission windows located at the terminus of each end section.

An improved device for promoting the emission of radiation by utilizing electrical energy to raise material from an initial state to an excited state is disclosed. The device includes enclosed means, including an elongated body section defining a first electrode and a pair of end sections, for enveloping a space occupied by the material. The device further includes a second electrode, adapted to receive electrical energy, disposed in fixed relationship with the first electrode for distributing the electrical energy thereto.
