← ScienceWhich risk increases during laser-induced breakdown spectroscopy (LIBS) of delicate archeological samples?
A)Material ablation exceeds analysis depth✓
B)Spectrometer resolution becomes insufficient
C)Laser coherence length drastically shortens
D)Plasma shielding diminishes signal strength
💡 Explanation
Material ablation risk increases with LIBS on friable targets because excessive laser energy causes vaporization during the ablation process, which is a fast phase transition. Therefore, critical sample information disintegrates, rather than undergoing controlled ionization.
