Abstract
Argon (Ar) atomic gaseous normal glow discharge is generated using two electrodes in low pressure in vacuum condition. The rate of change is constant a steady state in normal glow discharge. The shock wave is generated using the resonant absorption or induced emission in plasma state. The change of impedance is measured in terms of current or voltage of normal glow discharge. The aim of the work is to measure temporal profile voltage signal with the ionization probability and life time of two state lower and upper excited state in the plasma, theoretically calculated and experimentally. Results have been studied using Nd-YAG laser pumped tunable dye laser at pulsed width 7 ns and repetition rate 10 Hz. The opto-galvanic effect (OGE) is observed in normal glow discharge using the induced absorption and emission in one and two photon transitions. The change of impedance of normal glow discharge have been studied in temporal profile experimentally and calculated theoretically.
