Which consequence manifests when laser facet AR coatings fail?

💡 Explanation

An AR coating failure causes increased reflectivity at the laser facet, thus optical gain must increase to overcome losses. This raises the stimulated emission threshold because of enhanced reflectivity, rather than reduced resonance; these occur under different operational failures.
