Abstract : The results of a numerical simulation of the electrical discharge initiation by a pin discharge of an SF6:H2 reaction in a pulse HF laser system are given. A parameter variation of the amplitude and the temporal length and shape of the electrical discharge pulse is made. The resulting chemical reactions are simulated by the rate equation method for a reaction in a reaction cell, a laser cavity, and a laser amplifier. The effect of spatial inhomogeneity of the chemical reaction in a laser amplifier is considered. A pin electrical discharge laser system used in the initial experimental studies of the initiation of chemical reactions is described. Typical laser output pulses for the system are shown for SF6:H2:He reactants. (Author)
