TL;DR: In this paper, it was shown numerically that it is possible to control the bond distance of the RbCs dimer and create laser-induced oscillations using a single chirped pulse.
Abstract: We show numerically that it is possible to control the bond distance of the RbCs dimer and create laser-induced oscillations using a single chirped pulse. The implementation of the scheme involves the creation of a superposition of the 1 3
Σ
+ and 2 3
Σ
+ excited triplet electronic states. We assume that the molecule is aligned and the dynamics is initiated in the bound 2 3
Σ
+ state. The chirped pulse allows full population transfer and dynamic vibrational trapping in the 1 3
Σ
+ state. In the adiabatic regime the position of the vibrational wave packet can be fully controlled by the carrier frequency of the field, so that one can determine and fix the bond length at any desired value, or impose particular trajectories, depending on the choice of the chirp.

TL;DR: In this paper, an initial wave packet in the ground state, with optimized amplitudes and phases, can be used to enhance the yield of the reaction at faster rates, driven by a single picosecond pulse or a pair of femtosecond pulses resonant with the electronic transition.
Abstract: We study laser-driven isomerization reactions through an excited electronic state using the recently developed Geometrical Optimization procedure. Our goal is to analyze whether an initial wave packet in the ground state, with optimized amplitudes and phases, can be used to enhance the yield of the reaction at faster rates, driven by a single picosecond pulse or a pair of femtosecond pulses resonant with the electronic transition. We show that the symmetry of the system imposes limitations in the optimization procedure, such that the method rediscovers the pump-dump mechanism.
