(And it’s embedded below for your enjoyment.) The first half of the video is dedicated to the work on a laser welding system that doesn’t pan out in the end at all. But the missteps are worth ...

While lasers have long been viewed as a potential solution to advanced missile threats, current technology falls short of countering hypersonic missiles. Lasers face several challenges ...

Fibre lasers are lasers made from thin strands of a light-guiding glass. Atomic or molecular impurities introduced into the fibre when it is formed provide the optically active component ...

One solution could come from a technology called “free-space optics” (FSO), which uses lasers to transfer data through the ...

Lasers able to take down swarms of heat-seeking missiles have been successfully trialled on British aircraft for the first time in a boon for the Royal Air Force. The Ministry of Defence announced ...
