Spectroscopic peculiarities of electron-vibrational dynamics of diatomic molecules pumped by a femtosecond single photon field

摘要

Femtosecond electron-vibrational dynamics in a gas of diatomic molecules pumped by single-photon quantum field is theoretically investigated on the basis of the femtosecond pump-probe spectroscopy technique. The developed theory is applied for calculation of luminescence signal in a gas of Na_2 molecules and it is found that that there is a strong dependence between the form of the temporal spectrum of the signal and the optical density of the medium.
