Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific understanding of how stars, nuclear detonations and fusion energy work. For ...

Plasma, ionized gas and the fourth state of matter, makes up over 99% of the ordinary matter in the universe. Understanding its properties is critical for developing fusion energy sources, modeling ...

This animation shows a 3D rendering of plasma waves (blue) excited by a petawatt laser pulse (red) at Berkeley Lab's BELLA Center as it propagates in a plasma channel. Some of the background electrons ...

With dual lasers, researchers have accelerated a high-quality beam of electrons to 10 billion electronvolts in just 30 centimeters. The experiment gives scientists a 'frame-by-frame' look at how a ...

In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term – the metal is ...

The U.S. Navy has patented technology to create mid-air images to fool infrared and other sensors. This builds on many years of laser-plasma research and offers a game-changing method of protecting ...

Laser-plasma interactions represent a cornerstone of high-energy-density physics, where intense laser pulses interact with solid or gaseous targets to generate plasmas. This process underpins the ...

Laser plasma acceleration is a potentially disruptive technology: It could be used to build far more compact accelerators and open up new use cases in fundamental research, industry and health.

Magnetized plasmas have rarely been studied as nonlinear photonics media, yet they possess unique properties: Compared to unmagnetized plasmas, magnetization introduces additional resonances, which ...

The Pentagon is advancing work on plasma technology that can deliver intelligible speech to nearby locations and create non-lethal deterrents. Instead of beaming a flashing light or shouting over a ...
