Spatial-time density distributions of excited components (Xe*, He*, Xe/sup +/*, XeCl*m 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 concrete excited component is determined by two factors: the electric field inhomogeneity and the number of plasmochemical reactions leading to the formation of this component. The effect of the discharge layering is explained by the density gradients of excited components and the oscillating pumping.
