Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Jack of all trades, master of none, as the saying goes, and that’s especially true for PCB prototyping tools. Sure, it’s possible to use a CNC router to mill out a PCB, and ditto for a fiber laser.

Thulium fiber lasers, operating at a wavelength of 2 micrometers, are valued for applications in medicine, materials ...

While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon.

Ultrafast lasers have the advantages of high time resolution, high energy density, broadband spectrum, etc. Ultrafast lasers with high-energy and high peak power have been widely applied in industrial ...

In another step forward for laser weapons that brings to mind the Death Star's superlaser, Lockheed Martin has demonstrated a 30-kilowatt fiber laser produced by combining many lasers into a single ...
