| Abstract(in English) | A new technology is proposed for processing the phase information of electronic wave packet in device materials by use of femtosecond tailored pulses. We demonstrate strong dependence of wave packet dynamics in organic dye molecules on the amount and sign of the chirp. Especially in case of negatively-chirped pulses, the excited-state population is almost completely dumped just after excitation. On the contray, a Large amount of population remains in the excited state for positively chirped-pulses. We have performed a quantum mechanical calculation for an electronic two-level system coupled to a single vibrational mode, and successfully reproduced the experimental observation. |
