Abstract

When a focused laser beam falls on a multilayer thin-film coating, light is scattered from the volume over which the beam intersects the coating. Some of the light may be scattered into directions that correspond to guided modes of the thin-film structure. We report the observation of scattered light at locations removed from the region of incidence of the light on the coating, resulting from the secondary scatter of the guided scattered light. The shape of the pattern observed by secondary scatter clearly resembles the pattern expected for Rayleigh scatter from a point source. This observation has important implications for the design of scatter-measuring instruments as well as for the theoretical treatment of scatter from multilayer coatings.
