Abstract: It is shown experimentally that the mean energy of accelerated electrons generated by irradiating a dense target with a pair of 13-ns-delay femtosecond laser pulses forming radiation with an energy contrast of 100–500 and an intensity of about 10¹⁸ W/cm² increases significantly in comparison with the case of high contrast ~10⁶.
