Laser control of electronic transitions of wave packet by using quadratically chirped pulses

摘要: An effective scheme is proposed for the laser control of wave packet dynamics. It demonstrated that by using specially designed quadratically chirped pulses, fast and nearly complete excitation can be achieved without significant distortion its shape. The parameters pulse estimated analytically from Zhu–Nakamura theory nonadiabatic transition. If not too narrow or broad, then expected to utilizable multidimensional systems. applicable various processes such as simple electronic excitation, pump-dump, selective bond breaking, it actually numerically work well taking diatomic triatomic molecules (LiH, NaK, H2O) examples.
