Laser Induced Desorption of Atoms from Metal Particles: Mechanism and Applications
In the last few years, laser induced desorption processes have found a continuously growing interest. High intensity lasers have been used to study photon induced etching and ablation in microfabrication . Another example is laser-induced desorption of large molecules for mass and sequence analysis in biochemical and biophysical research . Furthermore many experiments try to evaluate the fundamental mechanisms underlying laser stimulated desorption of atoms or small molecules [3–5]. Major difficulties of such experiments are to identify the initial electronic excitation and to understand the bond breaking mechanism in detail.
