After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, ...

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

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain ...

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

Shadows are a natural consequence of opaque walls in an illuminated Universe. Light shines; photons travel until they hit an ...

But producing a small spot size with blue light has been tricky, says Hiroshi Ohno, who manages the laser development team to which Hagino belongs. A high brightness laser beam requires both high ...

Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line traversing the ...

To ask if a beam of light can make a shadow sounds like a sort of Zen paradox, but physicists have demonstrated the ...

"From there, we decided to conduct an experiment to demonstrate the shadow of a laser beam." To do this, the researchers directed a high-power green laser through a cube made of standard ruby crystal ...

In a recent study, researchers from the University of Ottawa have demonstrated a remarkable new phenomenon: a laser beam ...
