| Research Abstract |
The mid-infrared light serves as a powerful tool to drive molecular vibrational motions with high selectivity. In this project, we experimentally demonstrate that the vibrational ladder climbing efficiency is highly enhanced by the phase-shaping of the exciting mid-infrared pulses. In addition, we theoretically study the optimum waveform that gives higher efficiencies. We also demonstrate that it is possible to control the excitations of multiple vibrational modes in a coherent manner: the multipath interferences, which form the basis for any coherent control schemes, were manipulated for coupled oscillator system.
