Brookhaven researchers have revealed that a laser beam can cast a shadow through nonlinear optical processes, challenging ...

This could enable new tech for controlling light with light, opening doors to advanced fabrication, imaging, and illumination ...

"From there, we decided to conduct an experiment to demonstrate the shadow of a laser beam." First, the team shot a ...

Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the ...

The technique works because the green laser (wavelength 532 nanometers) changes the way the crystal responds to some other ...

Compound Semiconductor™ is an Angel Business Communications publication.

To do this, the researchers directed a high-power green laser through a cube made of standard ruby crystal and illuminated it with a blue laser from the side. When the green laser enters the ruby, it ...
