The eXawatt Center for Extreme Light Studies project aimed to create a large scientific
infrastructure based on lasers with giant peak power. The project relies on the significant …

Relativistic positron beams are required for fundamental research in nonlinear strong field
QED, plasma physics, and laboratory astrophysics. Positrons are difficult to create and …

A colliding microjet liquid sheet target system was developed and tested for pairs of round
nozzles of 10, 11 and 18 μm in diameter. The sheet's position stability was found to be better …

A linearly polarized Laguerre–Gaussian (LP-LG) laser beam with a twist index has field
structure that fundamentally differs from the field structure of a conventional linearly …

Multilayer dielectric gratings typically remove multiple-grating pillars after picosecond laser
irradiation; however, the dynamic formation process of the removal is still unclear. In this …

With ultrafast laser systems reaching presently 10 PW peak power or operating at high
repetition rates, research towards ensuring the long-term, trouble-free performance of all …

Описан проект XCELS (еXawatt Center for Extreme Light Studies), целью которого
является создание крупной научной инфраструктуры на основе источников лазерного …

Mid-spatial frequency wavefront deformation can be deleterious for the operation of high-
energy laser systems. When fluid cooled high-repetition-rate amplifiers are used, the coolant …

We present a technique to assess the spatial aberration content of a focused multiterawatt
laser when fired at full power. This method leverages the direct detection of electrons …

This paper addresses some of the of open problems in photonuclear physics which await to
be resolved using high-brilliance γ-ray beams, such as precise measurements of total or …
