Abstract :
A functional relation between the rms roughness of a rough surface and the laser induced damage threshold is found. In deriving this relation it is assumed that the effective exposed area of the rough surface plays a dominant role in the damage mechanism. It is shown that the existing emperical relation between the rms roughness of a rough surface and the surface damage threshold could be derived from this functional relation under certain conditions.
