Formation of nonclassical and non-Gaussian states of a strong electromagnetic field due to its interaction with free electrons produced by ionization of a target gas
E. S. Andrianov, Oleg I. Tolstikhin
Abstract
The authors study the effects of the interaction of a strong laser field with free electrons produced by strong-field ionization on the quantum state of the field. They show that under experimentally realistic conditions the interaction can strongly affect the quantum state of the field by squeezing and displacing the coherent state of the free field, which can result in the formation of nonclassical and non-Gaussian field states.
