Influence of the thermodynamical characteristics of liquids on the metal’s laser ablation process

Using liquid nitrogen and the liquid argon as a medium for pulsed laser ablation of metals, differences in the sedimentation of particles on the target’s surface was found. When used liquid argon Cu particles aggregates sedimentation process near the interaction of laser radiation with matter is more pronounced. It’s evident as the displacement and the broadening of the absorption band of the surface into red wave region of the spectrum relatively to the absorption spectrum of the ablated target in liquid nitrogen. Also, is detented the non uniform sedimentation of Au particles on a substrate surface in liquid argon. Obtain initial data of the dynamic changes of the absorption spectra of copper nanoparticles in ethanol by using the method of laser ablation in a liquid in the pressure range from 1 to 100 atm.
