A Russian FPV drone was destroyed after an encounter with a weird new Ukrainian weapon. Is this a high-powered laser or something else entirely?

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

As conflict escalates following the US and Israeli attacks on Iran, and Iran’s subsequent retaliatory strikes, reports have emerged that Israel may have used laser weapons to shoot down rockets fired ...

Since the discovery of lasers, laser outputs have been limited to simple wavefront profiles, such as Gaussian (with the highest intensity in the middle, and lower intensity towards the tails) and ...

The search for extraterrestrial life isn't limited to robots digging around in the giant sandbox we call Mars. In fact, scientists involved in SETI — the search for extraterrestrial intelligence — ...

A laser light beam passes between a loudspeaker-reflector array that creates a grating of air. The laser beam interacts with this grating and is deflected without contact. Using a novel method, beams ...
