Scientists at MBI and DESY create a plasma lens that focuses attosecond pulses, boosting ultrafast light experiments.

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is steered ...

You might expect that an opaque material will always hinder the transmission of light by absorbing or scattering any light that is shone on it. But by carefully preparing a beam of laser light, ...

A complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...
