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 ...

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.

A fiber laser can carve super intricate designs into any metal in just 10 seconds. The laser is getting so hot the metal is vaporizing away, yet it does nothing to our skin. As we play the video back ...

Looking for a high-performance, versatile, and precise fiber laser engraver to elevate your projects? The Omtech F-30 30W ...

If you’ve spent any time looking into laser engraving, you’ve probably come across the same question again and again: should ...

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and ...

It’s not often we feel that something we’re featuring is a genuinely new and groundbreaking technique, but a team from the University of Maryland’s Small Artifacts Lab may have done just that with ...

To carry information over long distances, the fiber must be extraordinarily clear. The magic behind an optical fiber’s transparency is a combination of material science and manu ...
