Two models of femtosccond laser-stimulated desorption (LSD) are considered. One is the LSD due to a coherent "giant" optical mode vibration created by a femtosecond laser pulse and the other is the predesorption induced by a femtosecond UVvisible laser.

A new mechwusm for desorption induced by an infrared laser is proposed An internal vibration of the adsorbate is excited by the laser and its energy uansferred to the desorption mode -an adsorbate-surface bond. Tlus mode coupbng wth surface phonons bgomes unstable. Such Instability leads to rupture
