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 ...

The use of lasers to route data streams through free air will find its place, but it's not likely to become a mainstream optical-networking technology. Free-space optics technology has been ...

3D printing of silica glasses and silica optical fiber preforms has recently been proved experimentally. One challenge of 3D printing silica optical fibers performance is how to extend the recent ...
