“…The ionization of atoms and molecules induced by the 2D laser fields shows richer electron dynamics processes. 30,31 In single elliptical fields the recollision trajectory of the ionized electron is elliptical. 32,33 By adjusting the relative phase between two orthogonal laser fields, the traveling time and the correlated electron dynamics can be controlled.…”

Strong laser pulses enable probing molecules with their own electrons. The oscillating electric field tears electrons off a molecule, accelerates them, and drives them back toward their parent ion within a few femtoseconds. The electrons are then diffracted by the molecular potential, encoding its structure and dynamics with angstrom and attosecond resolutions. Using elliptically polarized laser pulses, we show that laser-induced electron diffraction is sensitive to the chirality of the target. The field selectively ionizes molecules of a given orientation and drives the electrons along different sets of trajectories, leading them to recollide from different directions. Depending on the handedness of the molecule, the electrons are preferentially diffracted forward or backward along the light propagation axis. This asymmetry, reaching several percent, can be reversed for electrons recolliding from two ends of the molecule. The chiral sensitivity of laser-induced electron diffraction opens a new path to resolve ultrafast chiral dynamics. Published by the American Physical Society 2024

Carrier envelope phase sensitivity of photoelectron circular dichroism

Abstract: We report on a combined experimental and numerical study of photoelectron circular dichroism (PECD) induced by intense few-cycle laser pulses, using methyloxirane as the molecular example. Our experiments reveal a...
