When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool?

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 ...

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 ...

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.

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 ...

Using plasma to make lasers could make them more powerful and more compact. “We want lasers that can deliver a lot of light intensity, which allows us to do a lot of new, interesting physics. The ...

Taking place at the end of the semiconductor process flow, dicing is the process where the silicon wafer is finally turned into individual chips, or die, traditionally by means of a saw or laser. A ...
