Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

Now there’s a laser vape. Meet Luminary’s The Beam, a handheld, pocket-sized vaporizer that uses a class-1 laser you can actually see to heat weed extracts. I thought for sure it was a gimmick.

Now researchers at Toshiba and their colleagues reveal that quantum communications are possible across more than 250 ...

What turned into a tradition started on April 22, 2017, when I hiked the Rock Creek Road to Eilertson Meadow. Rock Creek is ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

After the US, Russia and China, India has successfully demonstrated a directed energy weapon or DEW — a 30KW laser beam capable of neutralising drones and static targets. It can also blind ...

Now, engineers at Duke University have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot ... Information could be encoded ...

This study examines interferometric techniques for distance measurement, focusing on innovations that mitigate air turbulence and refractive index fluctuations.

VCSELs offer a third option compared with conventional light emitting diodes (LEDS) and edge-emitting laser diodes (EELs).

[Upgraded 50 Numbered Adapters]: MCREHOTZ Laser bore sight kit with 50 adapters ... and gently press the button switch to emit a powerful green beam. With our upgraded 2 high-capacity CR2 ...
