Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

We don’t know what cats see when they see a red laser beam, but we know it isn’t what we see. The reaction, at least for many cats — is instant and extreme. Of course, your cat ex… ...

Is it wizardry? Physicists at the University of Konstanz have succeeded in changing the properties of a material in a non-thermal way with the help of light and magnons. The new process is not only ...

A 3D printer that uses lasers to build up an object in any order, rather than layer by layer, could produce more advanced designs than is currently possible.

The PHaSR was a big, bulky weapon which combined an infra-red laser with a laser dazzler to produce a repel effect.

A needle-shaped laser beam boosts the performance of a biomedical imaging method called photoacoustic microscopy 1. Photoacoustic microscopy uses laser-induced vibrations in biological tissue to ...

The laser beam itself is invisible to the human eye but, if the intensity of the laser pulse exceeds a threshold, the air breaks down into glowing plasma that emits visible light.
