← ScienceWhich consequence results when imperfect thin film deposition causes thickness variations on an antireflective coating for a high-power laser window?
A)Localized intensity interference maximum✓
B)Uniform decrease spectral reflection
C)Reduced thermal lensing absorption
D)Increased window mechanical strength
💡 Explanation
Localized intensity interference maximum can occur because variations in coating thickness cause constructive and destructive interference at different points, therefore creating hotspots on the window, rather than uniform changes or structural improvements.
