Energy and Phase Relaxation in Laser-Induced Admolecular Processes.

Abstract

Vibrational excitation and relaxation of a molecule adsorbed on a surface is investigated. The phase relaxation is seen to assist the laser-driving force in overcoming the anharmonic and/or detuning bottleneck. The incoherent thermalization processes in the initial stage of the admolecular multiphoton excitation are evaluated. It is found that phase relaxation (dephasing) due to the surface and admolecular perturbation plays an important role in the thermalization processes. Keywords: Energy relaxation; Phase relaxation; Laser-driven admolecule; Thermalization; Anharmonic bottleneck; Generalized master equation.
