Which consequence results when imperfect coherence in laser cutting steel?

💡 Explanation

Kerf width varies along the laser cut because imperfect coherence causes variations in the intensity profile. This results in inconsistent material removal; therefore, kerf width changes rather than consistent cutting seen with high coherence because less precision in location then contributes to that variance.
