Which consequence results from minimized coherence length during laser welding?

💡 Explanation

Reducing the coherence length minimizes interference effects through self-interference, because beam intensity fluctuates rapidly and energy is distributed. Therefore, less focused localized heating occurs, and the heat-affected zone is reduced, rather than causing other specific material changes.
