The effect of laser action on the structure of a model material — pure aluminum — is studied. Laser treatment of aluminum samples was carried out on a 15 J Nd:YAG laser, 10 pulses with a duration of 5·10–8 s. In the experiment, a transparent medium was used to exclude the influence of the thermal mechanism and create conditions for the shock-wave mechanism of action on the material. The structure was studied by transmission electron microscopy. After laser irradiation in pure aluminum, the formation of crystallographically oriented voids with transverse dimensions of 50 – 100 nm and a length of up to 500 – 800 nm was found. The mechanism of formation of such formations is discussed.
