INVESTIGATION OF ALUMINUM NITRIDE FORMATION PROCESSES IN PLASMA WHEN THE ALUMINUM ALLOY D16T IS SUBJECTED TO THE EFFECT OF DOUBLE LASER PULSES IN THE AIR

Abstract

The effect exerted by defocusing of double laser pulses on the formation of the component and charge composition in the surface laser plasma has been studied by the laser spark spectrometry (LSS) method. The possibility to increase the portion of variously charged aluminum ions in the surface laser plasma and also of AlN clusters when the target was subjected to a series of successive double laser pulses has been demonstrated.
