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 ...

Fiber lasers aren’t nearly as common as their diode and CO2 cousins, but if you’re lucky enough to have one in your garage or local makerspace, this technique for depositing thin films of metals in ...

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 ...

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

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 ...

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 ...

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

GWEIKE shares a practical fiber vs. CO₂ selection framework for metal and non-metal shops—focused on materials, throughput, and cut-quality workflows. JINAN ...

A focused beam of carbon dioxide laser light hits a sheet of uncoated paper. For a fraction of a second, the plant-based ...

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 ...
