计算结果表明它能有效地克服中间能级近共振所产生的多普勒背景，并有效地区分单光子饱和吸收讯号和双光子跃迁讯号。
The results show that the Doppler background due to the near resonance of the intermediate level is eliminated and the signal of two-photon transition can be distinguished from saturation absorption.
利用具有中间共振能级的无多普勒双光子相干选择激发来提高激光同位素分离的选择性和激发速率。
Selectivity and excitation rate of laser isotope separation can be enhanced by using the coherent selective Doppler-free two-photon excitation with intermediate resonant level.
