Theory of Laser-Simulated Surface Processes. 3. Desorption through Vibrational Excitation by an IR (Infrared) Laser

摘要

Desorption of an adatom from a solid surface through vibrational excitation by an IR laser is studied using a generalized master equation approach and the isomnesic approximation. A sharp transition from no desorption to almost instantaneous desorption is seen as the bound to continuum population transfer rate is varied. The critical rate increases linearly with laser power.
