The two partial beams overlap in such a way that the light blocks itself, so to speak: although the partially transparent mirror alone would actually reflect a large part of the light, this ...

The concept involves shining a beam, such as a laser, onto a material from above to pump it full of energy. This can alter the material's properties, making it transparent to other wavelengths of ...

Scientists make transparent materials absorb light. Moscow Institute of Physics and Technology. Journal Optica Funder Ministry of Education and Science of the Russian Federation (Minobrnauka) (3. ...

In the new research, members of Aristide Dogariu‘s group at the University of Central Florida, together with colleagues at the National University of Singapore, show that simple, unstructured light ...

The propagation of high-intensity light beams through transparent media can lead to unusual non-linear effects. Here Panagiotopoulos et al.show that a high-intensity ring-Airy beam transforms into ...

But it can be made transparent by illuminating it with a laser beam, called the 'coupling beam'. This makes it selectively transparent ... (packets of light) in a light beam.

In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two ...
