Tomography of asymmetrical laser-induced plasmas

Popis výsledku v původním jazyce

Asymmetrical laser-induced plasmas were investigated by a tomography approach based on the inverse Radon transform. Two distinct sources of asymmetricity were investigated: double-pulsed laser-induced plasmas in the orthogonal configuration and single-pulsed laser-induced plasmas under an inclined incidence angle. Both cases were observed at various delay times. The optical thinnes of the laser-induced plasmas was achieved by appropriately adjusting the pulse energies. High temporal resolution was achieved by a gated intensified charge-coupled-device camera. The asymmetrical laser-induced plasmas were investigated in terms of their total emissivity, spectrally resolved emissivity, and temperature. The latter was obtained by the Saha-Boltzmann plot method. The images required for the inverse Radon transform technique were obtained with a high angular accuracy and reproducibility provided by mounting the spectrometer on a high-precision nano-positioning rotary stage. The plasmas were induced in the cent
