RESEARCH OF Al2O3 AND Al NANOPOWDER FORMATION PROCESSES IN PLASMA UNDER THE INFLUENCE OF DEFOCUSED DUAL LASER PULSES ON ALUMINUM IN THE AIR ATMOSPHERE

The influence of the magnitude and type of defocusing of twin laser pulses on the purposeful formation of the component and charge composition of laser plasma under the influence of twin laser pulses on a target made of aluminum alloy AD1 (LSS-1 spectrometer) has been studied. It is shown that when...
