Abstract

It is shown that the appearance of micropores leads to an increase in the reflectance of aluminum-based alloy 1421 irradiated by laser pulses. The waveform of a reflected signal bears information on the onset and duration of the pore-formation process in the near-surface material layer during the action of a laser pulse.
