Abstract
Using the time-dependent wave packet method, Aulter-Townes splitting in the photoelectron spectra of four-level ladder Li2 molecules is theoretically investigated by two pump and one probe femtosecond laser pulses. Structure of the triple splitting is presented to analyze the information about a selective population of dressed states. It is found that regulating the intensity of laser pulse can control Rabi oscillation and thus tailor the splitting of three peaks. The population and energy of dressed states can be manipulated by changing the wavelength of the second pulse which can be interpreting using doubly dressed states. By adjusting the delay time between pump and probe pulse, one can control the population of the dressed states.
