Abstract:
    The invention discloses a sealed CuBr laser tube, comprising quartz base tube, quartz spacer rings, condensing bubble window, sealing end and discharging electrodes, where the quartz spacer rings 1-2mm thick are sintered equidistantly and coaxially on the inner wall of the quartz base tube between the discharging electrodes at two ends to divide the quartz base tube into several segments of 10-15cm long, and distilled CuBr working matter is uniformly placed in each segment to quartz base tube; the equrtz spacer rings can limit discharging activation region and maintains stable discharging; the discharging electrode is composed of quartz metal sealed terminal, quartz outer tube and quartz inner tube made with slots; the quartz inner tube is filled with pure copper particles to absorb dissociative bromine generated by CuBr discharging resolution and long time maintain stable discharging; as discharging, the CuBr diffused in the copper particles and other trace impurities are diffused and condensed on the inner wall of the quartz outer tube by the slots, assuring long time stable operation of the laser tube.
