| 摘 要： | 激光陀螺在低温下启辉电压过高,严重影响了其工程应用。为了确保低温下陀螺可靠启动,借鉴激光器领域内的预电离技术,提出一种激光陀螺辅助启辉方法。在陀螺谐振腔阴极附近放置一个辅助启辉发光装置,发射高能量光束照射陀螺谐振腔阴极内表面,增加阴极的次级电子发射能力,可以有效降低陀螺辉光放电电压。分别利用紫外气体发光管和紫外波段半导体发光二极管作为光源进行了陀螺启辉电压对比试验,结果表明:低温下两种光源均可有效降低陀螺启辉电压,但两者降低启辉电压的效率有差异,紫外灯效率在5%～30%之间,紫外波段的半导体发光二极管的效率在12%～28%之间,前者降低电压离散性较大,后者较为均匀,综合看,后者效果更为显著。

| Abstract: | The startup voltage of ring laser gyroscope(RLG) is too high in low temperature,which seriously limits the applications of RLG.In order to activate the RLG successfully in low temperature,an auxiliary start-up apparatus based on the preionization technique of laser field was proposed.The apparatus is placed near the cathode of the Zerodur glass block.It emits high-energy beams to illuminate the cathode surface and energize the secondary electrons,thus the glow discharge voltage of RLG can be effectively dec... |
