A method for modeling rotational nonequilibrium in HF(DF) laser systems that significantly reduces the computation time required for such calculations is described. With this formulation, an approximation can be obtained of the nonequilibrium optical gains of the individual v,J transitions without computing the individual populations for each v,J state, which appreciably reduces the number of integration variables. The predictions of a pulsed H(2)-F(2) laser model utilizing this approach are very similar to the predictions of a more complex model. The computational economy gained makes feasible parametric studies to improve understanding of the importance of rotational relaxation in laser calculations.
描述了一种用于对HF（DF）激光系统中的转动非平衡进行建模的方法，该方法显著减少了此类计算所需的计算时间。采用这种公式，可以在不计算每个v，J态的个体布居数的情况下，获得各个v，J跃迁的非平衡光学增益的近似值，这显著减少了积分变量的数量。利用这种方法的脉冲H₂ - F₂激光模型的预测结果与更复杂模型的预测结果非常相似。所获得的计算经济性使得进行参数研究以更好地理解激光计算中转动弛豫的重要性成为可能。
