Forming relativistic submicron electron bunches from plasma layers under the
action of a super-intense laser pulse was proposed and studied with computer
simulation. It was shown that the electron bunches can have a minimal thickness
of tens of nanometers and energies of tens to hundreds of MeV. The charge of
the bunches can be from picocoulombs to nanocoulombs. The role of the thickness
and profile of gas layer and laser amplitude on characteristics of the relativistic
electron bunches was studied. Simple analytical expressions were proposed to estimate
parameters of the electron bunches.
