In recent years, considerable efforts have been made toward the realization of quantum control of chemical reactions using so-called "laser pulse shaping". Experimental progress in areas such as spectral filtering and chirping techniques has enabled us to create pulse sequences, time-dependent amplitudes and frequencies for quantum control. Quantum control consists of manipulating nuclear wave packets to a desired reaction channel by the use of tailored pulses.
In this talk, recent progress in quantum control of photochemical reactions, that has been developed in our group is reviewed. The quantum control is based on an optimization theory of a linear time invariant complex system. The quantum control theory is valid not only for weak laser fields but also for strong fields. The quantum control theory is applied to several types of photochemical reaction dynamics such as IR photodissociation of hydrogen fluoride, and nonadiabatic transitions of sodium iodide.
