Abstract: 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.

Abstract: 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. 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.
Abstract translation: 一种同时产生多行排放并适用于光学数据处理系统的激光系统。 特别地，在第一实施例中，单一正列激光器包括两个部分，第一部分包括正柱氦镉激光器，第二部分包括正列氦氖激光器，第一和第二部分串联。 可以单独地激励每个部分，使得可以独立地控制由氦镉部分产生的由氦氖部分产生的红色激光和蓝色激光的最佳激发。 本系统还允许通过分开地控制镉的蒸发温度来分开镉蒸汽压力控制，并且还允许限制镉蒸气，由此蒸汽不会污染限制活性激光介质的光学窗口之一。 通过适当选择光腔参数，可以获得同时的红色和蓝色激光振荡，用于需要红色和蓝色激光辐射源的任何光学数据处理系统。 在第二实施例中，氦 - 镉部分被氦硒部分代替，由此串联激光系统能够产生红色，蓝色和绿色的多行激光辐射。

Abstract: A radiation emission device characterized by a cylindrical cathode enclosed by an elongated envelope having a body section and two end sections is disclosed. The device includes an anode terminal, coupled to the body section, which serves to provide electrical energy to excite metallic material inside the envelope. The device further includes a pair of cataphoresis terminals located along each end section to prevent the excited metallic material from drifting into contact with radiation transmission windows located at the terminus of each end section.
