Abstract: The effect exerted by defocusing of double laser pulses on purposeful formation of the component and charge composition of the laser plasma has been studied using the laser spark spectrometry (LSS-1 laser). It has been shown that there is a possibility to increase the portion of differently charged aluminum ions as well as of AlO and AlN nanoclusters in the laser plasma when a target of D16Т aluminum alloy is subjected to a series of defocused double pulses.
Keywords: AlO, AlN, pulsed laser deposition, laser plasma, laser spark spectrometry, multiply charged ions, double laser pulses.
