When atoms and molecules are ionized by strong laser fields, the liberated photoelectron can revisit the parent where it undergoes elastic and inelastic collisions. This rescattering mechanism lies at the heart of high-harmonic generation, nonsequential ionization and laser induced electron diffraction (LIED). During the last decade, the latter was successfully exploited to infer molecular structure, shown to be capable of observing motion with few picometers and few femtoseconds spatio-temporal resolutions, the intrinsic scales of atomic motion inside molecules. In this colloquium, I will provide an overview of LIED, our efforts in using this technique to visualize more and more complex molecules, the new physics uncovered in recent work and the method’s future.
