Abstract Enhancement of K α yield from a metal foil covered with metal rods of submicron sizes, with low aspect ratio, irradiated by a p -polarized femtosecond laser pulses of about 10 17 W/cm 2 intensity is demonstrated. Obtained relative increase in K α X-ray line emission is explained with a model of vacuum heating of fast electrons.
