ABSTRACT:
An improved metal vapor laser tube is comprised of an enclosure, preferably n an elongate tubular form, containing an amount of a metallic element. The material of the enclosure is selecteed to be electrically non-conductive and also for its ability to withstand elevated temperatures of the order of 1000.degree. C. The enclosure has at least one window capable of transmitting energy at the wavelength of emission of the metallic element contained within it. Two electrodes, preferably in the form of cylinders, are disposed at opposite ends within the enclosure in coaxial alignment with the major axis of the enclosure. An extension from the major axis of the enclosure is disposed proximate to each electrode and an electrical conductor connected to each electrode is sealed within substantially the entire length of each extension. Each electrical conductor is characterized as being of a strip configuration and having a substantially elongate elliptical cross-section.
A method of sealing the metallic conductor strip within a substantially tubular extension member comprises the steps of positioning the metallic strip within the hollow of the tubular member, then inserting a semi-cylindrical piece of fusible material into the hollow portion of the tubular member on each side of the metallic conductor strip, and finally simultaneously fusing the fusible material to both the metallic strip and the tubular member to form a unitary extension assembly.
