  Strong-field light-matter interactions initiate a wide range of phenomena in
which the quantumpaths of electronic wavepackets can be manipulated by
tailoring the laser field. Among the electronsreleased by a strong laser pulse
from atomic and molecular targets, some are subsequently drivenback to the
vicinity of the ionic core by the oscillating laser field. The trajectories of
these returningelectrons are bent towards the core by the ionic potential, an
effect known as Coulomb focusing.This process, studied over the past two
decades, has been associated with the long range influenceof the Coulomb
potential. Here we explore the structural properties of the Coulomb
focusingphenomenon. Specifically, we numerically study the sensitivity of the
returning electron dynamicsto the anisotropy of the ionic potential. We employ
orthogonally polarized two-color strong fieldsand chiral molecules, whose
asymmetric features lead to unambiguous fingerprints of the potentialon the
freed electrons. The Coulomb-focused electrons show an enhanced sensitivity to
chirality,related to an asymmetric attoclock-like angular streaking stemming
from field-assisted scatteringof the electrons onto the chiral ionic potential.
Anisotropic features of the ionic potential thusmonitor the motion of
Coulomb-focused electrons throughout their returning paths, shedding lighton
the structural properties of the interaction.
