In the single - photon resonance case, for large area input pulses, the spectral components oscillating around 32 appears in the spectrum due to the strong secondary excitation making the two - level model invalidity and the multi - level model should be used to describe this molecule
在單光子共振情況下，即入射脈沖頻率等於1 、 2能級之間的共振頻率，對大面積入射脈沖，由於強的二次激發的作用，電場頻譜中出現了在32附近振蕩的頻率成分， 32是2 、 3能級之間的共振頻率，說明對大面積入射脈沖二能級模型已經失效，需要採用多能級模型來描述分子介質。 -
