本文对已投入运转的千瓦级ＣＯ激光器放电区的等离子体特性作了探讨，从放电区等离子体的一些参数入手，计算了放电区的电子密度、电导率及等效电阻，并由此计算了放电区的注入功率。计算表明，对于典型的激光运转条件，放电区电子密度在１０１０／ｃｍ３左右，等效电阻约为几百欧姆。计算的等效电阻及注入功率与实验测量值基本一至
In this paper, the plasma characteristics of the discharge area of a kilowatt CO laser that has been put into operation are discussed. Starting from some parameters of the plasma in the discharge zone, the electronic density, the conductivity and the equivalent resistance of the discharge zone are calculated and calculated Discharge area injection power. Calculations show that for typical laser operating conditions, the electron density in the discharge zone is around 1010 / cm3 and the equivalent resistance is around a few hundred ohms. Calculation of the equivalent resistance and injection power and experimental measurements of basic one
