We theoretically investigate the Autler-Townes (AT) splitting in the photoelectron spectra of threelevel ladder K2 molecule driven by a pump-probe pulse via employing the time-dependent wave packet approach. The effect of the pump/probe laser intensity and wavelength on AT splitting is detailed studied. The magnitude of AT splitting increases with increasing the pump laser intensity, but does not vary with probe intensity. The double splitting with asymmetric profiles arises due to the nonresonant excitation. The double structure is transformed into one peak progressively as the pump is detune...
