Abstract

A large-power complex function quartz glass tube pulsed-xenon lamp and manufacturing method therefor, the pulsed xenon lamp is charactered in that its lamp is that it is a complex function quartz glass tube formed by the sealed fusion of a layer or multi-layer of pure quartz glass or multi-layer of cerium-doped silica glass layers. The pulsed xenon lamp preparation process steps include: (1) adopting a stratified weight producing technology to prepare a composite quartz glass weight material; (2) using an intermediate frequency furnace tube drawing machine to heat and draw the composite quartz glass weight material into an integrated complex function quartz glass tube; (3) adopting a sealing process to package electrodes in the complex function quartz glass tube; (4) implanting xenon to form a high-power pulsed flashlamp after vacuumizing. The pulsed xenon lamps of the invention not only has good mechanical properties, higher energy load, a long operational life; but also has a better radiation spectral characteristics, which can cut the near ultraviolet radiation below 340 nm, to meet the application requirements of the xenon lamp in the large pulsed laser device.

Description

Technical field: [0001] The invention relates to a high-power solid-state laser, especially a high-power compound function quartz glass tube pulse xenon lamp and its preparation method. Background technique: [0002] High-power pulsed xenon lamp is a commonly used laser pumping light source. Large-scale solid-state lasers must have megajoules of pulsed laser energy output, which puts forward higher requirements on the performance of laser pulsed xenon lamps. Pulsed xenon lamps must have high operational reliability and zero explosion probability. When the high-power laser is running, on the one hand, the strong current will generate a huge magnetic field, plasma shock wave and thermal shock to damage the quartz glass tube wall of the pulsed xenon lamp; on the other hand, the ultraviolet radiation near 300nm generated by the xenon plasma will make the neodymium Defects occur inside the glass. Therefore, the high-power laser needs to improve the mechanical strength and impa...
