Laser plasma discharge circuit can be simulated by Pspice through practical measuring result. We find that the circuit model of laser plasma should be simulated by a inductance in series with a resistor, furthermore in parallel with a capacitor. The value of the capacitor affect the oscillation frequency of the laser output voltage. The smaller the value of the equivalent capacitor, the less the rise time of the pulse voltage of the laser chamber. Also the rise time of the pulsed voltage of laser can be less when the stray inductance and transmission line capacitance are reduced. It is also found the time –invariant inductance is dependent on the total charge in the discharge area, the time-invariant inductance is dependent on the electric field in the laser chamber.
