Abstract

A multi-layer structure for controlling the transmission laser radiation including an array of polydispersing scatterers in an intermediate layer. The outer layer is made of a material which partially ablates when exposed to incident laser radiation, generating an irregular surface which initially scatters the incident laser radiation. The initially scattered radiation is transmitted to the intermediate layer containing the array of monofilament fibers which further scatters the laser such that combination achieves substantial attenuation of on-axis transmission of the laser radiation in an otherwise transparent structure.
