Findings

Coulomb potential significantly alters interference patterns.

The modified patterns differ notably from those predicted without Coulomb effects.

Results improve interpretation of strong-field holography experiments.

Abstract

Using the semiclassical two-step model for strong-field ionization we investigate the interference structures emerging in strong-field photoelectron holography, taking into account the Coulomb potential of the atomic core. For every kind of the interference pattern predicted by the three-step model, we calculate the corresponding structure in the presence of the Coulomb field, showing that the Coulomb potential modifies the interference patterns significantly.
