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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

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 ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...
