    Abstract: 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... Show More
