在低气压超声速cwHF化学激光放大器中 ,假设平动和转动非平衡交叉弛豫同时起作用 .对于气流介质的层流和湍流扩散混合两类流动模型 ,分别导出了饱和增益谱的表示式 ,并进行了数值计算 .计算结果表明 ,湍流扩散混合模型与实验结果符合得更好 .
In low-pressure supersonic cwHF chemical laser amplifiers, it is assumed that both translational and rotational unbalanced cross-relaxation functions at the same time.For two types of flow models of laminar flow and turbulent diffusion mixing, we derive the expression of saturated gain spectrum separately The numerical results show that the turbulent diffusion model is in good agreement with the experimental results.
