Photoionization of atomic hydrogen by a linearly polarized laser is numerically studied using a method based on an expansion of the wave function in angular-momentum components. The numerical method presented is quite efficient to compute photoioniza

We present a theoretical model for two-colour strong-field photodetachment of a negative ion. Our model can be solved analytically in a certain approximation. We discuss the phenomenology predicted by the model and test its numerical reliability unde

The absorption and reflection of a plane wave at the interface of a linear dielectric and a very dense saturable absorber is studied in situations where the linear refractive index has an imaginary part that is much bigger than its real part. In this

The steady-state propagation of a plane wave inside a nonlinear absorber is considered. We report a new kind of singularity that happens well inside the absorber. Some points appear inside the absorber where one component of the field is not continuo

Coherent high-order harmonic generation by an isolated two-level system is studied. A perturbative theory for the adiabatic regime is presented; the theory describes the plateau structure found experimentally in noble gases. Numerical results, withou

A numerical study of the reflectivity at a nonlinear interface is presented. We analyze situations in which the self-reflected wave appears inside the nonlinear material for various values of the incidence angle. The change of the incidence angle mak

We study multiphoton detachment for a one-dimensional ion model with a Dirac δ-function potential, numerically solving the Schrodinger equation. We analyze the influence of a multiphoton resonance just at the ionization threshold. The intensity depe

Multiphoton excitation of a model negative ion is studied. The model has only a single bound level, and we choose a photon frequency appropriate to five-photon photodetachment (before ponderomotive threshold shifts). Both of these characteristics are

The numerical solution of the Maxwell-Bloch equations describing the propagation of a plane monochromatic wave through a saturable absorber shows the appearance of a new kind of reflected wave generated inside the medium. This new phenomenon is descr
