Abstract :
Summary form only given. Recent progress in femtosecond laser pulse generation has made it possible to observe and manipulate intramolecular wave packets. The shape of a laser pulse may be optimized in order to create specially tailored material wave packets, thus steering (molecular and electronic) processes to desired product channels. In this study, we applied the optimal control approach to the process of separation of isotopes of diatomic molecules by exciting vibrational wave packets with femtosecond laser pulses. We developed a linear optimization procedure. The procedure is based on two-photon ionization.
