In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

The acceleration of a free electron by a laser is a long-time goal of solid-state physicists. Physicists have established that an electron beam can be accelerated by a laser in free space. This has ...

Controlled direct acceleration of electrons in very strong laser fields can offer a path towards ultra-compact accelerators. Such a direct acceleration requires rectification and decoupling of the ...

Researchers from Trinity College Dublin's School of Engineering have built a powerful new machine that lets us watch precisely what happens when tiny particles—far smaller than a grain of sand—hit a ...

The interaction between lasers and matter is at the forefront of new investigations into fundamental physics as well as forming a potential bedrock for new technological innovations. One of the ...

If Angus MacGyver was a particle physicist, he might face a challenge like this: Take a femtosecond laser and a fused quartz grating and make the world's most powerful particle accelerator. Despite ...

Osaka University-led research team achieves first realization of laser-generated energetic ions. Experimental setup with the large-area suspended graphene target. Click for info. Laser-driven ion ...

Electrically charged particles are relatively easy to accelerate using electric and magnetic fields. Neutral particles cannot be steered in the same way, which is a bit disappointing, since they are ...

Physicists in Japan and Taiwan have developed a compact, highly efficient method of generating high-energy ion beams by firing a laser pulse at a target made from two layers of graphene. Led by ...

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.
