Abstract:

An overdense plasma layer irradiated by an intense light can exhibit dramatic nonlinear-optical effects due to a relativistic mass-effect of free electrons highly-multiple hysteresises of reflection and transition, and emergence of gigantic rogue waves . Those are trapped quasi-soliton field spikes inside the layer, sustained by an incident radiation with a tiny fraction of their peak intensity once they have been excited by orders of magnitude larger pumping. The phenomenon persists even in the layers with soft boundaries, as well as in a semi-infinite plasma with low absorption.
