An experimental and theoretical study on the wave clipping of 355 nm laser is conducted by using the laser induced plasma shutter technique.

At present, the plasma shutter which has compact structure and good effect on the pulse shaping is a better method by which the high-quality short pulse can be obtained.

The Magnetohydrodynamic Simulation of a Coaxial Plasma Opening Switch;

The development of microsecond conduction time plasma opening switch (POS) with external magnetic field is outlined in the paper, which is applied to the inductance energy store system in pulse power technology.

The bipolar flow caused by the negatively charged metal grains from a microsecond plasma opening switch (POS) and the movement of the plasma made of the POS cathode material are considered to be responsible for the degradation of POS opening performance.

This model is proved to be practicable by the results of the particle simulation of plasma erosion opening switch involving complex field emission boundaries.

The simulation of electrical circuit with plasma erosion opening switch has been done on the basis of the combination of the erosion model with the world wide used electric circuit simulation software package, PSPICE.
