A comparison between the quantum ladder climbing and the classical autoresonance for robust molecular vibrational excitation from the ground state shows the disadvantage of shortening the exciting infrared laser pulse to the sub-picosecond range. Therefore, we demonstrated ladder climbing in molecule by a sub-nanosecond chirped laser pulse.
