Abstract
Discharge dynamics is crucial for self-sustained discharge pumped XeCl lasers. The stability of the discharge not only limits the energy deposition and laser pulse duration, but also plays a very important role in the laser output beam quality, e.g., intensity spatial distribution, beam divergence, etc. Many efforts have been made, both theoretically and experimentally, to improve discharge stability, and numerous papers devoted to this subject have been published. This paper presents some results of discharge dynamics studies on self-sustained XeCl lasers. The investigations were performed using a kinetic code that included the Boltzmann equation, species density rate equations, and circuit equations. The discharge process was divided into four stages: the initial stage, from spark gap switch-on to the static breakdown field; avalanche build-up stage, from the point at which the gas mixture resistance starts to decrease, to the quasi-steady-state discharge occurrence; quasi-steady-state stage, during which the resistance of the gas mixture and the voltage on the discharge gap are nearly constant; terminal stage, when the lasing stops.
