摘　　要：本文考虑了激光模式和泵浦光的空间分布,对线性驻波腔,我们建立了多模的麦克斯韦——布洛赫方程组,并由此导出了双模稳态条件下阈值泵浦功率和输出功率的表达式。讨论了双模Na_2激光器的运转行为,以及温度,Na_2蒸汽带长度及缓冲气体的压力对激光器的影响。得到了一些有用的结果。In this paper, we set the Maxwell-Bloch equations of multi-mode in the case of a standing wave laser field in a linear resonator, which consider the spatial Gaus-sion distribution of mode and pump distrbution. The equations of threshold pump power and output power under steadystate condition of two-mode are derived from the above equations. From these results, the behaviors of sodium dimer laser of two mode and the influences of temperature, length of sodium dimer vapour zone and press of buffer gas are discussed. Some very useful results are obtained
