We have calculated the effect of four-wave mixing of the main radiation pulse with the background radiation components on the value of the output radiation contrast in a chirped pulse amplification system of petawatt laser facilities. Formulae are pr

The reflectivity of a short-pulse laser at intensities of $2\times {10}^{21}\,{\mathrm{Wcm}}^{-2}$ with ultra-high contrast ( ${10}^{-15}$ ) on sub-micrometer silicon nitride foils was studied experimentally using varying polarizations and target thi

Reduced surface area targets were studied using an ultra-high intensity femtosecond laser in order to determine the effect of electron sheath field confinement on electron dynamics. X-ray emission due to energetic electrons was imaged using a ${K}_{\

We propose and use a technique to measure the transverse emittance of a laser-wakefield accelerated beam of relativistic electrons. The technique is based on the simultaneous measurements of the electron beam divergence given by v_{⊥}/v_{∥}, the
