Research highlights
Attosecond science
Photoionization of xenon in the 4d shell has been studied with attosecond pulses, revealing ultrafast electron-spin dynamics [Nature Communications 11, 5042 (2020)].
Chemical physics
Photo-induced fundamental processes in new perovskite solar energy materials are investigated in a vigorous research programme, where, for example, charge carrier and exciton dynamics in 2D perovskites has been studied in detail [Adv. Sci. 6, 1900548 (2019)].
Advanced imaging, Combustion diagnostics and Remote sensing
LLC researchers have developed a method (FRAME) that can record a series of images – a video – of a single event with record high temporal resolution (5 THz) and this unique ability has been demonstrated by recording a laser pulse as it propagates in space [Light Sci. Appl. 6, e17045 (2017)].
A high-resolution entomological LIDAR has been developed and used to explore activity anomaly of malaria vectors during pan-African eclipse [Sci. Adv. 6, eaay5487 (2020)].
Quantum physic and Quantum information
LLC researchers have recently demonstrated a concept for on-demand quantum memory with an experiment yielding a signal-to-noise ratio ~500 for weak coherent states, with an input of ~0.1 photons/pulse and a storage efficiency ~30% [https://arxiv.org/abs/2006.00943].
Plasma physics, Particle acceleration and X-ray generation
Ultraintense femtosecond laser pulses are used to drive plasma-based acceleration of electrons and protons. Intense short-pulse X-rays, produced by laser-accelerated electrons, are applied for novel diagnostics of industry–relevant sprays [Optica 7, 131 (2020)]
