Stepping up the waveguide length to kilometers, Milchberg says, is primarily a matter of boosting the doughnut-mode laser power. “The only issue is we don’t have a kilometer” to safely fire ...

Laser wave steers electrons in chemical bondsA Dutch-German team of scientists has succeeded for the first time in controlling a chemical reaction via steering the motion of electrons with ...

New high-resolution laser images show how wind and waves trade energy in two distinct patterns. This breakthrough could sharpen climate and weather predictions.

The researchers used an inkjet printing method to create the waveguide shown here. Sending laser light through the waveguide (red) allowed them to measure the waveguide's optical properties.

But current optical metrology requires bulky and expensive equipment to achieve delicate laser-wave control, creating a bottleneck for deploying streamlined, cost-effective systems.

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...
