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 ...

Researchers at Zhejiang University have found a way to stop performance-killing Auger recombination in perovskite lasers, using a clever additive during processing. Their method produced a ...

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 ...

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 ...

In 2022, scientists at California's Lawrence Livermore National Laboratory had a historic scientific breakthrough when they managed to achieve fusion "ignition" for the very first time. The process ...

Using plasma to make lasers could make them more powerful and more compact. Why people can have Alzheimer's-related brain damage but no symptoms ...

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 ...

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 ...
