Probability of Spontaneous Emission in Processes of the Above Threshold Ionization of Atoms
arXiv:1709.02978
Abstract
Expression for the probability of the spontaneous emission of high-order harmonics when the emitter phases are synchronized and are obtained in the region where the multiphoton approximation is applicable to the description of the ionization of an atom (where the adiabaticity parameter satisfies gamma > 1). The dependence of this probability on the main parameters of the pump wave and the atomic medium is established. Criteria for observing emission are formulated with the consideration of phase locking.
