Based on numerical solutions of the time-dependent Schrödinger equation,we theoretically investigate the photoelec-tron spectrum of hydrogen atoms ionized by a pair of ultrashort,intense,and orthogonally polarized laser pulses with a relative time delay in a pump-probe configuration.The pump pulse resonantly excites electrons from the 1s and 2p levels,inducing Rabi oscillations.The resulting dynamically enhanced Autler-Townes(AT)splitting is observed in the photo-electron energy spectrum upon interaction with the second probe pulse.In contrast to the previous parallel-polarization scheme,the proposed orthogonal-polarization configuration enables the resolution of dynamically enhanced AT splitting over a considerably wider range of probe photon energies.
