Multiphoton processes in quantum electronics

Michele Crance

Multiphoton stripping of atoms appears as the competition between step processes (one-by-one removal of electrons) and direct processes (several electrons being removed at the same time). These two types of processes cannot be distinguished by time or intensity dependence but have quite different coherence properties.

Electrons which are created in a multiphoton ionization process can collide with the ion from which they emerge.

The most important results of study of multiphoton ionization of atoms are reviewed. Discussions are presented of specific features of the process, theoretical methods of description of ionization of atoms in a strong light field, the basic principles of design of experiments in which intense laser radiation is used, results of investigation of direct and resonance processes of multiphoton ionization, and the mutual relation between multiphoton processes (multiphoton excitation and ionization) and various phenomena leading to perturbation of the spectrum of bound states of an electron in an atom under the influence of a strong light field.
