Formation of Oxidized Aluminum Nanopowders by Exposing Aluminum to a Series of Double Laser Pulses in Air

The effects of the interval between pulses and number double laser on component charge composition plasma formed by these acting an AD1 aluminum alloy target (LSS-1 spectrometer) are studied. It is shown that concentration Al ions products their interaction with atmospheric O2 N2 increase several orders magnitude if 7–16 ?s rather than a zero used. Formation studied as function pulse energy 10 ?s. strongest lines for III observed small (~15) consecutive in series 53 mJ. intensity decreases about five times increases above certain level (10–20) because active molecules atoms at exit micronozzle when channel shape changed. nanopowders coated layer oxide produced irradiating 15 per point have sizes mainly 50–60 ?m.
