Die chemischen Wirkungen der Röntgenstrahlen kommen auf ganz andere Weise zustande als die chemischen Wirkungen des Lichtes. [J. Eggert: Lehrbuch der physikalischen Chemie in elementarer Darstellung. Sechste Auflage, S. Hirzel, Leipzig; Seite 654]
Single ≤1 kJ pulses from a high-power laser are focused into molecular gases to create large laser sparks [1-5]. This provides a unique way to mimic the chemical effects of high-energy-density events in planetary atmospheres (cometary impact, lightning) matching the natural energy-density and plasma-volume scaling of such events in a fully-controlled laboratory environment.

The research in the field of x-ray spectroscopic diagnosis of hot dense plasma is based primarily on high-resolution spectrometers [1, 2] developed in the Institute of Physics ASCR, v.v.i. Current efforts concentrate to two main areas.
X-ray fluorescence holography with atomic resolution is a promising tool for imaging of local atomic structures in materials without translational periodicity (e.g. small clusters of atoms or moleculas). However, this holographic method suffers from serious drawbacks (low signal-to-noise ratio in measured holograms, virtual atoms and strong artefacts in reconstructed images). The whole text »
The electron phase space evolution in a non-relativistic and homogeneous laser plasma generated by a nanosecond laser in a near infrared region in the presence of stimulated Raman scattering is investigated by a numerical simulation. The mechanism of electron acceleration in the potential wells of the plasma wave accompanying the Raman back-scattering is analyzed in a 1D Vlasov-Maxwell model. The dominant wave modes are both the backward and the forward propagating Raman waves, each accompanied by a daughter electrostatic wave. The whole text »
