Nonlinear optical memory effect [PDF]
Optics Letters, 2019 Light propagating through random media produces characteristic speckle patterns, directly related to the large multitude of scattering events. These complex dynamics remarkably display robustness to perturbation of the incoming light parameters, maintaining correlation in the scattered wavefront.

Extracting sub-cycle electronic and nuclear dynamics from high harmonic spectra
Scientific Reports, 2021 We present a new methodology for measuring few-femtosecond electronic and nuclear dynamics in both atoms and polyatomic molecules using multidimensional high harmonic generation (HHG) spectroscopy measurements, in which the spectra are recorded as a ...

Symmetric spatio-temporal focusing of ultrashort pulses [PDF]
EPJ Web of Conferences, 2020 Simultaneous spatio-temporal focusing of few-cycle pulses is usually performed by stretcher-compressor configurations causing pulse-front tilt. By shaping and superimposing two reciprocal sub-beams, opposite tilts can compensate each other.

Single-Cycle Nonlinear Optics [PDF]
Science, 2008 Nonlinear optics plays a central role in the advancement of optical science and laser-based technologies. We report on the confinement of the nonlinear interaction of light with matter to a single wave cycle and demonstrate its utility for time-resolved and strong-field science.
