Which consequence results when excessively pulsed laser ablates PMMA?

💡 Explanation

Increased roughness results because plasma formation during pulsed laser ablation exceeds the polymer's damage threshold; therefore, irregular bursts cause localized, non-uniform etching rather than controlled material vaporization because the material properties change with excessive energy.
