LiDAR, was used to “redraw” the remains of the city, along the lower western slopes of the Suikerbosrand hills near Johannesburg. Karim Sadr

How we recreated a lost African city with laser technology

Technology which located Mayan cities has been used to rediscover a southern African city from the 15th century.
Example of nonlinear effect which can be observed in an optical fiber. All the colors of the rainbow are generated at the output while only one color is present at the entrance. We’re talking about supercontinuum.

And suddenly, the dam broke, letting the grains of light gush forth…

To understand what is happening in an optical fibre, physicists can mimic a rupture of the flow of grains of light – the photons – thanks to a laser device.

Using lasers to make data storage faster than ever

The speed comparison between today's technology and femtosecond spintronics is like comparing the fastest bullet train on Earth to the speed of light.

Timeline: the history of gravity

It's taken centuries for our understanding of gravity to evolve to where it is today, culminating in the discovery of gravitational waves, as predicted by Albert Einstein a century ago.

We transformed living cells into tiny lasers

Using fluorescent dye, researchers figured out how to turn cells into lasers – with applications for cell tagging and tracking as well as medical diagnoses and therapies.

Light technologies illuminate global challenges

During these dark winter months, spare a thought for artificial lights. From strings of lights adding holiday cheer to artificial sunlamps alleviating seasonal affective disorder, they brighten our days…
