It is shown that collisionless absorption of the circularly polarized intense laser pulses normally impinging on the overdense plasma can lead to the vacuum heating of the electrons at the sharp vacuum-plasma interface. The suggested mechanism could lead to the heating of plasma at the periphery of the laser spot rather than at its center. This fact can be applied for verification of the considered effect in real experimental conditions.
PACS: 52.38.Dx – Laser light absorption in plasmas (collisional, parametric, etc.) / 52.38.Kd – Laser-plasma acceleration of electrons and ions / 52.50.Jm – Plasma production and heating by laser beams (laser-foil, laser-cluster, etc.)
