Scientists have successfully miniaturized a powerful erbium-based biber laser on a silicon-nitride photonic chip. Since typical erbium-based fiber lasers are large and difficult to scale down, the ...

A single-fiber linear-cavity laser integrated with multifunctional devices was proposed and demonstrated for fiber dual-comb acquisition speed enhancement. This setup enabled flexible control of the ...

This project, sent in by [Henk], goes through a few different ways to make a solder stencil using a vinyl cutter, a CO2 laser, and a fiber laser. The project starts with identifying a method to ...

Researchers at the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) say that they have built a thulium fiber laser capable of emitting 1.91 kW - nearly double the typical output ...

Fair warning: watching this hybrid manufacturing method for gear teeth may result in an uncontrollable urge to buy a fiber laser cutter. Hackaday isn’t responsible for any financial difficulties that ...

Semiconductor laser diodes (SLDs) are often packaged with a photodiode. The output current from this photodiode can be monitored to regulate the output power intensity of the laser diode. SLDs, ...

A recent study has examined the effects of laser surface texturing (LST) on pre-sintered zirconia using a surface transition machine (STM). Researchers compared the impact of LST on zirconia’s surface ...

Penn engineers have taken quantum networking from the lab to Verizon’s live fiber network, using a silicon “Q-chip” that speaks the same Internet Protocol as the modern web. The system pairs classical ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through ...
