Double chaos
Physicists fight laser chaos with quantum chaos to improve laser performance
To tame chaos in powerful semiconductor lasers, which causes instabilities, scientists have introduced another kind of chaos.

Surprise slow electrons are produced when intense lasers hit clusters of atoms
Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, overturning current theories.
X-rays from tabletop lasers allows scientists to peer through the ‘water window’
Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays.

10 years of the trapped rainbow: the revolution of slow light
A decade on from suggesting light can be dramatically slowed - or even stopped - by new materials, Ortwin Hess reviews the progress and applications.
Ultrafast method for measuring ultrafast lasers reveals complex waveforms
Imperial and Oxford researchers have demonstrated a novel method for measuring the evolving waveforms of laser pulses just a few femtoseconds long.
New ultrafast laser technique set to probe fundamentals of chemical reactions
Reactions caused by light, such as photosynthesis, can now be captured in greater detail thanks to a technique developed by Imperial researchers.
