Abstract

The constructive interference that is responsible for the diffractive behavior of a grating or the reflective properties of a multilayer dielectric stack can enhance the electric field above values that would occur in unstructured homogeneous material, with consequent practical implications: regions of high field may initiate multiphoton ionization of bound electrons that trigger localized damage. Our poster presented examples of fields expected in some diffractive grating structures, and we contrasted the electric fields expected within high efficiency dielectric gratings and multilayer dielectric stacks with the fields expected around high efficiency metallic gratings.
