Vibrational Ladder Climbing in NO Using Ultrashort IR Laser Pulses
Chirped excitation of an electronic ladder system has shown complete transfer of the population to the top-level of the ladder system. Similar excitation of vibrational ladders in molecules may provide a tool for state-selective chemistry. Experimental results on the climbing of the anharmonic vibrational ladder of nitric oxide (NO), by irradiating the molecule with femtosecond infrared (IR) pulses, are presented. The free-electron laser FELIX is tuned to l = 5.3
