Hole with diluted density in the presence of self-generated magnetic fields

The collapse behavior of the fields and hole with diluted density described by the nonlinear coupling equations in laser-produced plasma are investigated in the condition of non-static limit. The results show that the nonlinear plasma currents give rise to intermittent magnetic fields, leading to collapsing hole with diluted density. The self-generated magnetic field is very important for the formation of hole with diluted density. The resulting density perturbation rate is very similar to that observed experimentally.
