ZERO-DIMENSIONAL HYBRID MODEL FOR ANALYSIS OF DISCHARGE-EXCITED XECL LASERS

A powerful zero-dimensional hybrid model to study the positive column of a glow discharge used as an excitation medium for XeCl lasers is pr esented. This model was employed using a numerical code including thre e strongly coupled parts: electric circuit equations (electric model), electron Boltzmann equation (particle model), and kinetics equations (chemical kinetics model). From this hybrid model, kinetics and electr ical parameters of Ne-Xe-HCl laser discharge mixtures have been discus sed and analyzed. Calculated discharge current and voltage are also co mpared with available theoretical and experimental results. The good q ualitative agreement observed shows the validity of the present model which can used as an efficient tool for the investigation of the homog eneous excimer laser discharge.
