His first attempts either blew right through the film or did absolutely nothing, but eventually he had the bright idea to move the laser farther from the LDPE. This put the beam out of focus ...

or Laser Telescope Blaster as he calls it, works for long distances. His solution lies in some surprising physics: the larger the diameter of the beam, the more slowly it will diverge. So he used ...

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.

The Jena-based team, led by Till Walbaum, have used spectral beam combining - a technique also deployed in laser weapons development - to raise the output power of systems emitting light at ...

An engineer adjusts the beam-control optics that ride in the nose of the Airborne Laser Testbed, a modified Boeing 747-400F. The optics stabilize and shape the weapon laser’s beam as it is aimed ...

Israel’s experimental air-defense system known as the Iron Beam uses laser technology to strike down drones and rockets, but military analysts say the device needs U.S. support to improve its ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital ...

A weapon that uses a high-power laser beam rather than a missile to destroy a target. Also called a "directed energy weapon." THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction ...
