YouTuber and inventor Styropyro has built and tested a 250-watt handheld laser device. The system is roughly 50,000 times more powerful than standard commercial laser pointers, Styropyro claims in his ...

YouTuber Drake Anthony, who goes by "styropyro," has created what he claims is the world's strongest handheld laser. According to Anthony, the legal limit of a laser pointer is 5 milliwatts, so he ...

The U.S. Navy has identified laser weapons as an urgent capability need, and after many years of development, it is moving rapidly to deploy advanced laser capabilities in the near term to the fleet.

A tiny, levitated bead is at the core of an unprecedentedly bright laser that shoots particles of sound instead of light. Just as a ray of light is made up of many particles called photons, sound ...

Using plasma to make lasers could make them more powerful and more compact. You can upgrade your immune system, but not in the way you think ...

[Mark aka Mokey] borrowed his friend’s open-frame laser engraver for a while, and found it somewhat lacking in features and a bit too pricey for what it was. Naturally, he thought he could do better ...

Sadly, the usual CO 2-powered suspects in the DIY laser cutter market are woefully incapable of cutting metal. Sure, they’ll cut the heck out of plywood and acrylic, and most will do a decent job at ...

On July 28, defense giant Lockheed Martin announced it was planning to scale its current laser technology up to a 500-kilowatt-class laser. This would be a substantial increase in output over the ...

The microsphere, levitated by the dual beam optical tweezer (green), is driven by the active optomechanical system (red) to generate nonlinear phonon lasers (coloured waves). Meanwhile, the injected ...
