The lumped element equivalent circuit model of an alpha discharge of a RF excited slab CO2 laser (RESCL) is presented. The amplitude and phase of voltage distributed along the length of the electrode of a RESCL is calculated by computerizing lumped parameter circuit equation according to the equivalent circuit model in resonant discharge state. The least relative voltage amplitude undulation along the electrode capable of being obtained in our experimental RESCL is about 1.27%. The result is different from that got by using distributed parameter theory[1].The formulas of the parameters of RLP and E/Pgas of a RESCL with microcosmic measured parameters according to the equivalent circuit model have been derived.These fomulas are different from that described in the paper[2]. An experimental RESCL was built and the uniform RF discharge and CO2 laser are obtained.
