Vibrational Excitation of an Adbond by a Short-Pulsed Laser.
Abstract
A system of a phonon-damped adbond, coherently excited by a laser, is considered. The effect of a series of laser pulses is compared with effect of a continuous-wave laser. Consider an adsorbed atom in a vibrational bond, driven by a laser, and damped due to the lattice vibrations of the substrate. We approximate the vibrating adatom by a one-dimensional oscillator, for the motion perpendicular to the surface. The interaction between the adatom and the substrate is given by the potential between the atom and the nearest surface atom.
