STATE-SELECTIVE CONTROL FOR DISSIPATIVE VIBRATIONAL DYNAMICS OF HOD BY SHAPED ULTRASHORT INFRARED-LASER PULSES

Ultrafast state-selective manipulation of populations under the contro l of shaped picosecond infrared laser pulses is investigated by means of computer simulations within the reduced density matrix formalism be yond the Markov approximation for the HOD molecule coupled to an unobs erved quasi-resonant environment. The laser-driven dissipative quantum dynamics in a classical electric field is simulated for discrete vibr ational levels within a two-dimensional model of the HOD stretches in the electronic ground state. Efficient population transfer with the pr obability up to 80-90% is demonstrated on a picosecond time scale in t he presence of the environmental degrees of freedom which reduce the l ifetimes of vibrational bound states into a picosecond time domain.
