We present experimental data for the carbon equation of state (EOS) at Megabar pressures obtained by laser-driven shock waves. Experiments were performed at the PALS and LULI laboratories using carbon samples with two different values of initial dens

For conventional wavelength (UV–vis–IR) lasers delivering radiation energy to the surface of materials, ablation thresholds, etch (ablation) rates, and the quality of ablated structures often differ dramatically between short (typically nanosecon

We report the preliminary result of the application of the collisional Ne-like soft x-ray laser as radiation source to induce DNA damage. The goal of this experiment was a test bed study of the damage yields induced by soft x-ray radiation in dried p

We report on recent laser driven shock experiments performed at the PALS laboratory in Prague. In the first series of experiments, the ablation pressure at 0.44 μm has been measured at irradiance up to 2×1014 W/cm2. The diagnostics consisted in the

Shock pressure generated in aluminum targets due to the interaction of 0.44 μm (3 ω of iodine laser) laser radiation has been studied. The laser intensity profile was smoothed using phase zone plates. Aluminum step targets were irradiated at an int

The efficiency of ablation induced in poly(methyl methacrylate) (PMMA) by single soft X-ray pulses emitted from Z-pinch and laser-produced plasmas was determined. X-ray ablation of PMMA was found to be less efficient than that of teflon (PTFE). Nonth
