Nonlinear interference and electron dynamics: Probing photoelectron momentum distribution in strong-field ionization — •Danish Furekh Dar1,2 and Stephan Fritzsche1,21Helmholtz Institute Jena, Fröbelstieg 3, 07743 Jena, Germany — 2Friedrich-Schiller-Universität Jena

Nonlinear interference in the interaction of intense laser pulses with atoms profoundly affects the photoelectron momentum distribution (PMD). We theoretically show that the interference pattern in the PMD arises from the interaction of electron with the fundamental frequencies concealed within the pulse. Nonlinear interference also imprints distinctive features on the ionization spectrum, providing valuable information about electron dynamics and phase relationships within the laser pulse. Additionally, the augmentation of optical cycles induces a distinct confinement in the PMD.
