A change in the spatial distribution of the laser beam by virtue of its reflective interaction in many directions by a non-specular (non-mirror like) surface or other reflecting medium.
Divergence
The angle at which the laser beam spreads in the far field; the bending of rays away from each other, as by a concave lens or convex mirror.
