A cube oriented aluminum single crystal is highly deformed by plane strain compression, then micro-drilled by 200 fs or 8 ns laser pulses, and finally analyzed by the electron back scattering diffraction technique. Recrystallized and recovered zones are observed as signatures of the HAZ. A typical value of 1.5 µm is found in the femtosecond regime of illumination, whereas for nanosecond pulses a value of 25 µm is measured. These results are in accordance with previous experiments and numerical simulations. %G English %L ujm-00118081 %U https://ujm.hal.science/ujm-00118081 %~ UNIV-ST-ETIENNE %~ EMSE %~ UNILIM %~ INSTITUT-TELECOM %~ IOGS %~ CNRS %~ LAHC %~ SPCTS %~ SMS-ENSMSE %~ MPE-ENSMSE %~ PECM-ENSMSE %~ PARISTECH %~ MPM-ENSMSE %~ IPAM %~ INC-CNRS %~ IRCER %~ UDL %~ INSTITUTS-TELECOM %~ IMPEO %~ TEST2-HALCNRS
