Abstract :
Spatial-time density distributions of excited components (Xe*, He*, Xe/sup +/*, XeCl*, free electrons) and the lasing intensity were measured by the pulse-dye-laser absorption (gain) probing of the active medium of a XeCl discharge laser. Some general regularities of the local deposition rate dynamics and active medium formation processes have been obtained. The influence of the electric field and preionization nonuniformities on the discharge profile is discussed. It is shown that the spatial profile, for the number of plasmochemical reactions leading to the formation of this component. The effect of the discharge layering is explained on the basis of the density gradients of excited on the basis of the density gradients if excited components and the oscillating pumping.<>
