Intense Laser Interactions: Higher Order Resonances and Hot Electrons
The kinetic energy spectrum of electrons produced by multiphoton and above threshold ionization of atoms has been studied in detail for nearly two decades. Much has been learned about the mechanisms behind the gross and fine structures present in these spectra over a wide range of experimental conditions. Theoretical models ranging from very simple and semiclassical to sophisticated quantum treatments have been developed to explain a great deal of the phenomena observed in experiments.
