Near a welding robot, which consequence results when debris contaminates laser mirrors?

💡 Explanation

Debris on laser mirrors introduces scattering, causing the beam's **diffraction** to increase rapidly, and therefore, the beam divergence becomes worse near the target; this is especially true, rather than other effects, due to the coherence of laser systems.
