The effect of the laser light on the discharge development characteristics in the active medium of an ArF excimer laser is investigated using a one-dimensional fluid model including laser-light-induced photo-ionization and photodetachment processes. These processes are found to have a significant effect at times after the maximum in the laser output signal. For example, the laser-light-driven interactions increase the bulk electron number density by a factor of two and the electric field adjacent to the cathode by a factor of 1.5. Near the anode, the field changes from slightly negative at early times to extremely positive near the end of the laser pulse, resulting in electron drift in the direction of the bulk plasma. This tendency of the field to change sign at the anode is not observed when photon processes are neglected. This strong field enhancement suggests the generation of a filamental instability at the electrodes, as is indicated by experiments.
