Abstract
The formation of holes under the action of single laser pulses was studied in thin-sheet samples of aluminum alloy 1420 with ultrafine-grained (UFG) and coarse-grained (CG) structures. It is established that, at the same laser pulse energy, a hole in the UFG samples is formed in a shorter period of time than in the CG samples of the same thickness.
