Abstract

We report on studies of plasmas, formed by the interaction of 80 fs, 1 J Ti:Sapphire laser pulses with solid matter. The laser intensity was 5 × 10¹⁹ W/cm². The K_{α1, 2} X-ray emission spectra at ≈4.5 keV were measured using a toroidally bent GaAs (400) crystal spectrometer with the spectral and spatial resolutions of 0.3 eV and 4 μm, respectively. A Si (220) polarizer was used for determining the polarization properties of the recorded emission. A strong polarization dependence of the K_α satellite emission was observed, which may indicate an anisotropy of the relativistic electron velocity distribution. Also, electrons with energies in the range of 500 keV-13 MeV were detected using an electron spectrometer.
