Аннотация: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 10(18) W/cm(2) increases significantly in comparison with the case of high contrast similar to 10(6).
