Effect of Pulse Temporal Profile on Autler--Townes Splitting in Photoelectron Spectrum

The effect of pulse temporal profiles on the Autler--Townes (AT) splitting in photoelectron spectra is theoretically studied by employing the time-dependent wave packet method for a rotational Na₂ molecule. The AT splitting which results from the sufficient Rabi oscillations is affected by the pulse profile and molecular alignment. The AT splitting may be observed only by utilizing proper pulse profiles with a certain intensity.
