Abstract

High-energy electrons above 1 MeV are observed from underdense plasmas produced by high power and short laser pulses. The emission of the high-energy electrons seems to have a correlation with an appearance of a complex filamentary structure along the axis of the laser beam. The obtained dependence of the electron energy on the laser power of p^(0.7-1.4) and on the gas density of P_gas^(1.8-2.3) suggests the presence of the stochastic heating of the electrons.
