In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Radiative shocks are a class of shock waves in which the transport and deposition of radiation play a central role in modulating the shock’s structure and dynamics. These phenomena are not only ...

Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...

A nanophotonic mode-locked laser built on lithium niobate emits a beam of green laser light. Lasers have become relatively commonplace in everyday life, but they have many uses outside of providing ...

The world’s only net-positive fusion experiment has been steadily ramping up the amount of power it produces, TechCrunch has learned. In recent attempts, the team at the U.S. Department of Energy’s ...
