Which outcome results when an imperfection causes uneven **thin-film interference** within a multilayer optical coating on a high-power laser lens?

💡 Explanation

Localized thermal runaway results. Imperfections cause constructive interference, therefore increasing absorbed light as the **irradiance enhancement** generates heat within the coating, escalating into thermal damage rather than simply affecting collimation because excessive heat is generated inhomogenously.
