One-dimensional steady-state structures at relativistic interaction of   laser radiation with overdense plasma for finite electron temperature
  One-dimensional steady-state plasma-field structures in overdense plasma are studied assuming that the electron temperature is uniform over plasma bulk and the ions are stationary. It is shown that there may exist solutions for electron distributions with cavitation regions in plasma under the action of ponderomotive force
