Abstract

The evolutions of density disturbance and fields near plasma critical surface in laser-irradiated solid target are investigated in basis of nonlinear dynamics model. It is found that the collapse of fields is faster in non-static limit case than that in static limit case due to its collapse enters supersonic stage. The intense electric field forming from its collapse drives electron density disturbance that generates electron cavity, simultaneously intense low frequency magnetic field is induced in cavity. The results are useful for studying plasma cavity in fast ignition in ICF and ion acceleration.
