Carbon and oxygen have a high absorption contrast. This is used to study biological and mineral samples via the “water window“, which has a spectral range between λ = 2.3 – 4.4 nm. Transmission X-ray ...

A laser pulse through a capillary filled with hydrogen plasma creates a wake that can accelerate an electron beam to a billion electron volts in just 3.3 centimeters. The same LOASIS accelerating ...

The new table-top system may offer a cost-effective and convenient alternative to large-scale, multi-million-dollar facilities such as synchrotrons or free-electron lasers, which, until now, were the ...

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 ...

Researchers have successfully combined a table-top laser-based extreme high-order harmonic source for short-pulse soft-X-ray absorption spectroscopy in the water window with novel flatjet technology.

Laser plasma accelerators offer the potential to create powerful electron beams within a fraction of the space required by conventional accelerators – and at a fraction of the cost. Their promise for ...

The experiment was conducted at the Laboratoire d'Optique Appliquée with the ‘Salle Jaune’ Ti:Sapphire laser system, which delivers 5 J, 30 fs (FWHM) pulses at 1 Hz centred around a wavelength of 813 ...

There is keen interest in generating intense, coherent, soft-X-ray beams for scientific and measurement applications 1. Here, we report the demonstration of soft-X-ray lasers with essentially full ...

A new way to generate bright beams of coherent extreme UV radiation using a table-top setup has been developed by scientists. This could be used to produce high resolution images of tiny structures at ...

(Nanowerk News) Researchers at Swinburne University of Technology have discovered a new way to generate bright beams of coherent extreme UV radiation using a table-top setup that could be used to ...
