Abstract The program presented calculates quasienergy spectra of one-electron atoms or ions undergoing multiphoton ionization in an intense two-colour field or ionization in a strong static electric field. The electron is initially bound by a single Coulomb potential or by a superposition of a short-range potential and a Coulomb potential. Besides quasienergies, the program can obtain rates of photoionization in specific ATI channels and angular distributions of photoelectrons, in the approximation where ... Title of program: STRFLO Catalogue Id: ADIY_v1_0 Nature of problem The dynamics of multiphoton processes in atoms irradiated by an intense laser pulse depends on the underlying spectrum of complex quasienergies, which the program can calculate for hydrogenic systems and for one-electron models. The calculation also yields a wave function describing the decaying atom; it can be used for computing multiphoton ionization rates differential in the energy and in the angle of ejection of the photoelectron.
