Effect of the laser-induced forward rescattering on the low-energy photoelectron momentum spectra of hydrogen atoms

Rescattering induced by intense laser fields is one of the dominant processes in strong-field physics. It was usually described classically or semiclassically. In the present work, we show that the fanlike structures exist in photoelectron momentum distributions even though using the strong field approximation model with the short-range potential. We also investigate the dependence of fanlike structures on the laser intensity. We have performed the detailed analysis on the photoelectron momentum distributions through the quantum-orbit theory.
