Strong, localized electrostatic fields created in laser plasma interactions act as a source of hot electrons. We have derived analytical formulas based on adiabatic invariants for explaining of the main characteristics of the electron spectra found in test particle calculations and in full wave-particle simulations. The electrons are treated relativistically. Simple models for phenomenological description of nonlinear wave damping are discussed.
