摘　　要：用一维动力学模型对千瓦级横流自持放电ＣＯ激光器工作特性进行了计算。得到了ＣＯ和Ｎ２分子的振动态粒子布居。利用常数增益光强平均法计算了三程Ｎ形折叠腔的输出功率的温度特性及谱线分布情况，得到了振转跃迁激光输出的振动带及转动支线的详细情况。The performances of one kilowatt transverse flow self sustained discharge excited CO laser have been calculated by means of the one dimension kinetic model.The vibrational distribution function of CO and N 2 molecules were obtained.With the method of constant gain,the authors calculated the output power and detail spectrum distribution.A good agreement of the calculations with the experiments is reached.
