Semiconductor lasers use the optical properties of semiconducting materials to produce coherent light. Electrons and their positive-charge counterpart called holes are injected into an optically ...

Laser-produced plasmas are plasmas produced by firing high-intensity beams of light. Laser-produced plasmas have been used to create short bursts of x-rays and to accelerate particles — so-called ...

Abstract: Laser-induced periodic surface structures (LIPSS, ripples) are a universal phenomenon and can be generated on almost any material upon irradiation with linearly polarized radiation. With the ...

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 A5 is the seductive, sloped-roof cousin of the understated A4 and is available as a hatch-equipped Sportback, two-door Coupe, and drop-top Cabriolet. The Sportback is the most popular, squaring ...

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 ...

The Federal Aviation Administration’s (FAA) brief restriction of airspace above El Paso, Texas, and southern New Mexico resulted from the Pentagon planning to test anti-drone technology despite the ...
