We present recent results on ionization of atoms and molecules in sculpted two-color laser fields. Technique enables to create electron wavepackets wit sub-fs duration by highly non-linear tunneling process [1] and actively control its dynamics on sub-fs time scale [2]. Consequently, the interference patter between wavepacket propagating in oscillatory laser field can be resolved by means of the angular-resolved photoelectron spectroscopy. Additionally, we identify the ionic Coulomb field influence on propagating electron wavepackets by comparing experimental data with results of strong-field approximation calculations and solving of time-dependent Schrödinger equation.
