A pulsed xenon lamp and its sealing method

Abstract

The invention discloses a pulse xenon lamp and a sealing method of the same. The pulse xenon lamp and the sealing method of the same are characterized in that two ends in a quartz tube in a xenon lamp are respectively provided with an electrode I and an electrode II along a transverse central axis; the electrode I and the electrode II are bilaterally symmetrical with a longitudinal central axis of the quartz tube; the tail of the electrode I at the right end of the longitudinal central axis of the quartz tube is fixedly connected with an electrode cap, a patchplug and a cable wire along the transverse central axis successively; the structure of the left end of the longitudinal central axis of the quartz tube is the same as the structure of the right end of the longitudinal central axis of the quartz tube; the electrode cap sleeves the outside of the port of the quartz tube, and active solders are filled between the electrode cap and the port of the quartz tube, and are heated to more than 600DEG C in a vacuum environment being less than 5*10-3Pa; and when the active solders are fused and are fully reacted with quartz glass, direct non-coupling sealing of the electrode cap and the quartz tube is completed. The sealing method of the pulse xenon lamp is easy to realize automation and large scale production of xenon lamp sealing, is simple and stable in the sealing process, is high in the vacuum sealing performance of the sealing area, and is high in structural intensity. The xenon lamp can bear large current, and the service life and working reliability of the xenon lamp are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of special electric light sources, and in particular relates to a pulse xenon lamp and a sealing method thereof. Background technique [0002] High-power pulsed xenon lamps are widely used as pump light sources for large lasers. In order to withstand the high-temperature plasma generated instantly by the xenon lamp, the lamp tubes are all made of quartz glass. The sealing between the quartz tube and the electrode assembly is the most critical link in the production of pulsed xenon lamps. The sealing process and sealing quality not only affect the life of the xenon lamp, but also have an important impact on the structural strength of the xenon lamp. The most commonly used sealing methods are transition glass sealing and molybdenum foil (or molybdenum cylinder) sealing. [0003] The transition glass sealing technology is to first use the special glass that can be matched with the metal to realize the tight s...
