Abstract

A simple model taking into account the effect of electron temperature is derived to define the plasma-field structures which may arise during relativistically intense laser interaction with overdense plasmas. We show that there exist multilayer solutions with electron cavitation, allowing for both relativistic and ponderomotive nonlinearities. The influence of finite electron temperature on such structures is studied. Examples of these plasma-field structures for the cases of an infinite plasma and a plasma layer are presented.
