Which risk increases when a pulsed laser with poor coherence illuminates a rough metal surface?

💡 Explanation

Reduced material ablation efficiency occurs because the interference patterns lead to uneven energy distribution; therefore, ablation is inconsistent rather than uniformly vaporizing material with ideal laser energy due to coherence.
