We know In the nanosecond ablation of metals in experimental conditions typically used for LIBS, the principal mechanisms of material removal are surface normal evaporation and phase explosion. The particle size distribution of the ablated mass depends on the ablation mechanism. The ablated mass may be in the form of atomic-sized vapor if thermal evaporation dominate, whereas it may be in the form of a mixture of vapor and large particulates from a phase explosion process. Now my question is: How can we effectively atomized (form of atomic-size) the particle ejection from sample in the phase explosion case?
