Inducing changes in the bond length of diatomic molecules by time-symmetric chirped pulses

Bo Y. Chang, Seokmin Shin, Ignacio R. Solá

We show numerically that it is possible to change the structure of a simple molecule, that is, a diatomic molecule, where the bond length is modified at a precise timing with symmetrically chirped laser pulses. In the adiabatic regime, the process is fully time reversible, making it possible to design slow vibrations with large bond elongations. The scheme relies on the preparation of a separable state of both nuclear and electronic degrees of freedom with predominant amplitude on the dissociative (antibonding) electronic wave function. Shorter laser pulses can be used to dynamically induce larger bond elongations, preparing a highly excited vibrational wave packet in the ground potential as the laser is switched off.

Tailoring of vibrational state populations with light-induced potentials in molecules

Mirta Rodríguez, Kalle‐Antti Suominen, B. M. Garraway

Summary form only given. We propose a method for achieving highly efficient transfer between the vibrational states in a diatomic molecule. The process is mediated by strong laser pulses and can be understood in terms of light-induced potentials. Light-induced potentials were also key to understanding APLIP (adiabatic passage by light induced potentials), where a wave packet is guided from one ground vibrational state to another. However, in the new process we show how to target specific vibrational states with strong short pulses. In addition to describing a specific molecular system, our results show how, in general, one can manipulate the populations of the different quantum states in double well systems.

Adiabatic Passage by Light-Induced Potentials in Molecules

B. M. Garraway, Kalle‐Antti Suominen

We present the process of adiabatic passage by light-induced potentials for transferring a wave packet from one molecular potential to the displaced ground vibrational state of another. The process uses a counterintuitive sequence of light pulses to couple three molecular states. It shares many features with the process of stimulated Raman adiabatic passage, such as high efficiency and insensitivity to pulse parameters. However, in the former there is no two-photon resonance, and the main mechanism for the transport of the wave packet is a light-induced potential.
