Which consequence results when a continuous-wave laser lacks coherence during laser material processing?

💡 Explanation

Reduced material ablation efficiency occurs because the laser relies on constructive interference, a result of coherence, for focused energy transfer. Lacking coherence diminishes this effect, therefore requiring multiple passes rather than an efficient single beam application because the energy density is decreased, and heat dissipation increases.
