Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening ...

Flashing a laser into the cockpit of an airplane can distract, even temporarily blind pilots. Minnesota incidents have increased by more than 180% since 2015.

After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life — and found that laser beams ...

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

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

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

With the help of a ruby cube and two laser beams, researchers made one ray of light cast a shadow when illuminated by the ...

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

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

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 ...

founded Blue Laser Fusion in Palo Alto, California, in November. Partners include Hiroaki Ohta, a former CEO of drone maker ACSL Ltd. The start-up, which raised $25 million (about 3.5 billion yen ...
