Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear ...

A compact fiber-based system has been developed to compress mid-infrared laser pulses to 187 femtoseconds using low input power. By integrating a holmium-doped ZBLAN photonic crystal fiber within a ...

This study addresses the issue of cracking in WC/Ni60 cladded layers with high WC content. The effects of different WC contents on the formation quality, microstructure, and microhardness of WC/Ni15 ...

Abstract: Semiconductor laser diodes (LDs) typically use lattice-matched epitaxial layers as waveguide cladding materials. We describe a new LD architecture in which the upper cladding layer is ...

The winter months, when people spend significantly less time in the sun, are typically known as “laser season” by skin experts—if you’re considering a treatment, now is a great time. “We perform laser ...

The unexpected and ultimately short-lived flight ban near El Paso this week stemmed from disagreements within the federal government over the use of a high-energy laser weapon system to take down ...

The Pentagon authorized an anti-drone laser against a suspected Mexican drone over El Paso, Texas, this week. NPR's Steve Inskeep talks to Thom Shanker of the Project for Media and National Security.

Minutes before midnight on Feb. 11, the Federal Aviation Administration shut down the airspace over El Paso for 10 days − longer than the airspace closure after the Sept. 11 attacks − prompting ...

The Defense Department has been aggressively pursuing laser weapons and defense systems, a push that gained significant attention this week when the use of an anti-drone laser system led to the ...

Bryan Bedford wasn’t happy. Against the expressed wishes of the FAA, officials from Customs and Border Protection had used the Pentagon’s high-energy laser weapon to shoot down what it thought was a ...
