The ability to precisely control the various properties of laser light is critical to much of the technology that we use today, from commercial virtual reality (VR) headsets to microscopic imaging for ...

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

When a semiconductor material called black phosphorus is hit with intense laser light, the behaviour of its electrons is found to change. The discovery opens a route to time-dependent engineering of ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

UPTON, NY—Lasers are intense beams of colored light. Depending on their color and other properties, they can scan your groceries, cut through metal, eradicate tumors, and even trigger nuclear fusion.

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest photonic chips go a step further by splitting a single laser into a ...

Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The ...
