Ullschmied In a mixture of molecular gases with compositions (CO2–N2–H2O and CO–N2–H2O) and total pressure close to that of the EarthÕs early atmospheres, a centimeter-sized plasma was created by focusing a single 85-J, 450-ps…

Spectroscopic investigations of high-energy-density plasma transformations in a simulated early reducing atmosphere containing methane,

Civiš Large-scale plasma was created in gas mixtures containing methane using high-power laser-induced dielectric breakdown (LIDB). The composition of the mixtures corresponded to a cometary and/or meteoritic impact into the early atmosphere of either Titan or…
