In massive particle accelerators, sub-atomic particles (like electrons) are sped up to super-high speeds comparable to the speed of light towards a target surface. The collision of accelerated ...

High harmonics: a NIR pulse (red) is focussed, and high harmonics are generated in a gas jet that is placed before or behind the NIR focus. The generated XUV light (violet) has a size and divergence ...

Laser ion acceleration uses intense laser flashes to heat electrons of a solid to enormous temperatures and propel these charged particles to extreme speeds. These have recently gained traction for ...

A laser plasma accelerator uses a laser pulse (red and blue disks, extreme right) to create a wake through a plasma, creating strong electric fields. Like surfers on a wave, free electrons ride the ...

A supersonic jet of helium gas (red, upper panel) greatly increases plasma density upstream of the hydrogen-filled capillary (blue). In the lower panel, the black curve shows density increasing, then ...
