TL;DR: In this article, the authors report the generation of isolated soft X-ray attosecond pulses with an Xray free-electron laser, which has a pulse energy that is millions of times larger than any other source with a peak power exceeding 100 GW, with a unique combination of high intensity, high photon energy and short pulse duration.

TL;DR: It is shown that high-harmonic generation can produce higher photon energies and flux by using higher laser intensities than are typical, strongly ionizing the medium and creating plasma that reshapes the driving laser field.

TL;DR: In this article, an experiment with atoms at nanokelvin temperatures has produced the remarkable observation of light pulses travelling at velocities of only 17 m s−1. The large optical nonlinearities seen in this system may open up new opportunities in quantum optics.

TL;DR: A novel strategy for generating sheet jets in vacuum using high resolution 2-photon 3D printing and generated 1.49 ± 0.04 μm thickness, stable, and <λ/20-flat jets in isopropanol under normal atmosphere and under vacuum at 5 × 10-1 mbar.

TL;DR: In this article, the authors proposed and demonstrated a new technique to conduct transient absorption spectroscopy with broad bandwidth attosecond pulses with the aid of ghost imaging, recovering sub-bandwidth resolution in photoproduct-based absorption measurements.
