Disentangling intra-cycle interferences in photoelectron momentum distributions using orthogonal two-colour laser fields

Xinhua Xie, Tian Wang, ShaoGang Yu +7

We use orthogonally polarized two-colour (OTC) laser pulses to separate quantum paths in multiphoton ionization of Ar atoms. Our OTC pulses consist of 400~nm and 800~nm light at a…
