Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

Australian-US team says wavefront-shaping of input light lifts power threshold for SBS scattering by an order of magnitude. A narrowband laser beam shaped by a spatial light modulator excites many ...

The laser module is one of the least reliable components in such a system. For that reason, it remains in a convenient pluggable form, enabling easy and inexpensive replacement. If designers were to ...

A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240105, discusses a high-resolution tumor marker detection based on microwave photonics demodulated dual wavelength fiber laser ...

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 ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new ...

It’s a rare person who can pick up a cheap laser pointer and not wield it like a lightsaber or a phaser, complete with sound effects. There’s just something about the “pew-pew” factor that makes ...

Mesh aims to mass-produce optical transceivers for AI data centers.
