Which consequence results when airborne dust contaminates laser optics?

💡 Explanation

Dust absorption leads to localized heating, therefore thermal lensing causes beam distortion, rather than increasing power or enhancing reflection which would mitigate rather than exacerbate the problem, because coherence isn't directly affected by dust.
