SPECTRAL STUDIES OF THE AlO AND AlN RADICALS FORMATION PROCESSES IN THE PLASMA WHEN OXIDIZED ALUMINUM IS SUBJECTED TO SERIES OF DOUBLE LASER PULSES

Abstract

The effect of an additional laser pulse on the desired formation of the component and charge composition of the surface laser plasma has been studied by the laser spark spectrometry method with the use of a LSS-1 spectrometer. The possibility to increase a portion of AlO and AlN radicals in the plasma when the target is subjected to a series of double laser pulses has been demonstrated. The influence exerted by laser parameters on the formation of the desired ionic and molecular composition of the plasma has been shown.
