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

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

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

Researchers create a visible shadow using only a laser beam, an achievement that seemingly defies conventional physics.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out ...

Conventional knowledge presupposes that if two light beams cross, nothing of note happens. But in an experiment, as detailed ...

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

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

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

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

The green laser acts like an ordinary object while the blue laser acts like illumination. The interaction between the two light sources created a shadow on a screen that was visible as a dark area ...

That’s why different types of lasers and light therapies are used to treat acne. The following explains what the different types of lasers and lights can and cannot treat. Blue, red, and blue + red ...
