金属蒸气激光器的直流放电特性

DC DISCHARGE CHARACTERISTICS OF METAL VAPOR LASERS

金属蒸气激光器利用He、Ne、N_2和Ar作缓冲气体,在高功率电平下的直流放电特性被首次测得。实验表明,He气是用于直流预热的最佳缓冲气体。在200mmHg的He气压和1A的放电电流下,有多于5kW的电功率被注入到等离子体管中去。等离子体管温度在短于1h的时间内达到1400℃的高温。

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.
