Abstrakt: 3 Conclusion The main goal of this doctoral thesis is to investigate the possibility of synthesis of simply organic molecules from inorganic gases such CO,CO2N2,NH3,CHa,H2O,H2, using the large laser sparks. The laser sparks provide a unique way to mimic the chemical effects of high-energy-density events in planetary atmospheres (cometary impact, lightning) matching the natural energy-density, its spatio-temporal evolution and plasma-volume scaling ofsuch events in a fully-controlled laboratory environment. Laser induced dielectric breakdown was induced by Š1kJ laser pulses in molecular gases and mixtures related to various planetary atmospheres. We believe that the single-shot experiments realized at the high-power laser facility simulate more realistically high-energy-density atmospheric events than similar experiments conducted with electrical discharges or experiments using low- energy pulses from high-repetition-rate lasers. In our case three different gaseous mixtures were used for these purposes; the strongly.reduced mixture NH3-Cř{4.H2-H2o, medium-reduced mixture CO-N2-H2O and mildly-reduced mixture CO2-N2-H2O. For all kind of my experiments the emission spectra w€re measured in different spectral regions. The motecular bands of CN and C2 radicals dominates in the visible spectra taken from the...
