Design of optimal laser pulses to control molecular rovibrational excitation in a heteronuclear diatomic moleculeAuthors: Sitansh Sharma,Harjinder Singh Journal: Journal of Chemical Science (link) Volume: 124 Volume Number: 1 Pages: 99-104 Date: 2012-01-27 Report no: IIIT/TR/2012/32 AbstractOptimal control theory in combination with time-dependent quantum dynamics is employed to design laser pulses which can perform selective vibrational and rotational excitations in a heteronuclear diatomic system. We have applied the conjugate gradient method for the constrained optimization of a suitably designed functional incorporating the desired objectives and constraints. Laser pulses designed for several excitation processes of the HF molecule were able to achieve predefined dynamical goals with almost 100% yield.
