TY - JOUR A2 - Dalimier, Elisabeth AU - Parigger, Christian G. AU - Oks, Eugene PY - 2010 DA - 2009/08/09 TI - Laser-Induced Optical Breakdown in Methane: Diagnostic Using H-Gamma Line Broadening SP - 936385 VL - 2010 AB - Measurements and analysis are reported of Stark-broadened profiles of the H-gamma line emitted from plasma formed by Laser-Induced Optical Breakdown (LIOB) in a pulsed methane flow. Electron densities Ne are deduced for 18 instants of time in the range between 0.4 and 2.1 microseconds after LIOB and for 2 different gas pressures. The obtained values of Ne are in a good agreement with the corresponding values found previously from Stark-broadened profiles of the H-alpha and H-beta lines.
