A single-ended electrode cylindrical inert gas discharge lamp and its manufacturing method

Abstract

The invention discloses a single-end electrode cylindrical inert gas discharge lamp and a manufacturing method thereof. The single-end electrode cylindrical inert gas discharge lamp comprises a cylindrical quartz glass lamp body. There is an annular space formed between the inner cylinder and the outer cylinder, a first ring electrode and a second ring electrode are symmetrically sealed at both ends of the ring space, and the power connection end of the first ring electrode protrudes from one side of the lamp body , the power connection end of the second ring electrode protrudes from the other side of the lamp body and connects to the wire, the wire extends through the central cavity of the inner cylinder, and the extension end of the wire and the power connection end of the first ring electrode are located on the same side of the lamp body . The invention realizes uniform irradiation of pumping light, effectively improves light energy utilization rate and reduces heat loss. When applied to high-power lasers, the laser conversion efficiency can be greatly improved, which is conducive to the manufacture of relatively high-energy lasers, and can reduce the manufacturing cost of laser systems and reduce the volume of equipment.

Description

technical field [0001] The invention relates to a gas discharge lamp, in particular to a single-end electrode cylindrical inert gas discharge lamp and a manufacturing method thereof, belonging to the technical category of high-power laser in the technical field of lasers. Background technique [0002] In the field of high-power laser technology, the laser medium in the laser is excited by lamp pumping. At present, a high-pressure inert gas discharge lamp is used as the pumping source of the laser. Its working principle is to emit light by means of an arc between two poles to realize the pumping function. However, the existing inert gas discharge lamps are all in the shape of straight rods, the uniformity of pumping is poor, the transmission loss of pumping light is large, the pumping efficiency is low, the heat loss is large, and the utilization rate of light energy is low, resulting in low laser conversion efficiency. . [0003] In view of the shortcomings of the above-m...
