金屬蒸氣激光器的直流放電特性
DC DISCHARGE CHARACTERISTICS OF METAL VAPOR LASERS
-
摘要: 金屬蒸氣激光器利用He、Ne、N2和Ar作緩沖氣體,在高功率電平下的直流放電特性被首次測得。實驗表明,He氣是用于直流預(yù)熱的最佳緩沖氣體。在200mmHg的He氣壓和1A的放電電流下,有多于5kW的電功率被注入到等離子體管中去。等離子體管溫度在短于1h的時間內(nèi)達(dá)到1400℃的高溫。

Abstract: DC discharge characteristic for metai vapor laser at high power level were mea-sured for the first time using He, Ne, N2, Ar as buffer gases. It was found that He is the best buffer gas for DC discharge preheating. More than 5kW electric power was injected into plasma tube at 20 mm Hg He pressure and 1A ctive anodic oxidation, by which the ununiform. tube reached to 1400℃ in less than an hour. -
