Nonlinear beam cleaning in spatiotemporally mode-locked lasers

In the last few decades, only temporal modes have been considered for mode-locked fiber lasers using single-mode fibers. Mode-locked single-mode fiber lasers offer advantages due to their high-gain doping, intrinsically single-spatial ...

Sensors get a laser shape up

A simple method developed at KAUST uses laser beams to create graphene electrodes that have better performance than those produced through older methods.

New optical method paves way to breath test for cancer biomarker

Researchers have developed an extremely sensitive, yet simple optical method for detecting formaldehyde in a person's breath. Because formaldehyde is being studied as a potential biomarker for lung and breast cancer, the ...

Dissecting colloidal glasses using laser as a lancet

Bo Li and Kai Kou, Research Fellows of IBS Center for Soft and Living Matter, together with Walter Kob, Professor of University of Montpellier and Institute Universitaire de France, and Steve Granick, Director of the IBS ...

Researchers demonstrate attosecond boost for electron microscopy

A team of physicists from the University of Konstanz and Ludwig-Maximilians-Universität München in Germany have achieved attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave ...

New tractor beam has potential to tame lightning

Lightning never strikes twice, so the saying goes, but new technology may allow us to control where it hits the ground, reducing the risk of catastrophic bushfires.

Researchers develop nonlinearity-induced topological insulator

Researchers from the University of Rostock have developed a novel type of nonlinear photonic circuitry in which intense light beams can define their own path and, in doing so, render themselves impervious to external perturbations. ...
