Missing-rung problem in vibrational ladder climbing

Dissociation of HeH+ in the electronic ground state using shaped mid-IR laser pulses

“…For a one-dimensional Morse oscillator, genuine ladder climbing has been demonstrated, leading to a synchronous, successively complete population and depopulation of excited vibrational states. 21,22 An additional advantage of VLC is that phase modulation elongates the pulse duration, which leads to a decrease in peak intensity and consequently, reduced ionization. However, the majority of theoretical studies on dissociation via VLC have been conducted in one dimension [20][21][22] (for an exception, see ref.…”
