Quadrature properties of high harmonics emitted by two-level atom
Year: 2020
Type: preprint
Abstract: We analyse the quadrature mean values and variances of high harmonic photons, emitted by a classically driven elementary quantum source of radiation. This fundamental system is modelled with a two-level atom. The quadrature mean values and variances are calculated for harmonic modes in the near-field. Numerical results imply the presence of weak squeezing in each harmonic mode, more pronounced in even harmonics. Approximate time-evolution of the collective electromagnetic field is calculated, and the electric field-variance of the scattered pulse-train is given.
