- Аннотация: This paper describes the study of hot electron generation under the action of intense (1018W/cm2) femtosecond pulses onto the surface of a solid target, in the presence of a long pre-plasma, which varied with different spatial extents and densities. The corona was formed by pre-pulses with varied intensities and temporal profiles (amplified spontaneous emission (ASE) and short pre-pulses). The most efficient fast electron acceleration, to energies well beyond the ponderomotive potential, was observed if the ASE was able to form to the extent of 100 lm a slightly undercritical plasma. Energy of accelerated electrons underwent further growth if the laser pulse duration increased from 45 to 350 fs at constant energy fluence. The experimental results were supported by numerical simulations using 3D3V Mandor PIC code.
