Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the
emergence of a novel generation of femtosecond x-ray sources. Based on radiation from …

Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

In the 2015 review paper 'Petawatt Class Lasers Worldwide'a comprehensive overview of
the current status of high-power facilities of was presented. This was largely based on facility …

The use of ultra-high intensity laser beams to achieve extreme material states in the
laboratory has become almost routine with the development of the petawatt laser. Petawatt …

The frequency doubling of laser light was one of the first new phenomena observed
following the invention of the laser over 50 years ago. Since then, the quest to extend …

This review presents the technological infrastructure that will be available at the Extreme
Light Infrastructure Attosecond Light Pulse Source (ELI-ALPS) international facility. ELI …

The development of attosecond technology is one of the most significant achievements in
the field of ultrafast optics over the past decade. Since the first experimental demonstration …

Under the effect of even simple optical components, the spatial properties of femtosecond
laser beams can vary over the duration of the light pulse. We show how using such …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

When an intense femtosecond laser pulse hits an optically polished surface, it generates a
dense plasma that itself acts as a mirror, known as the plasma mirror. As this mirror reflects …
