Abstract

A development of a method for analysis of diffraction grating with a multilayer dielectric coating is presented. The new method enables the calculation of the diffraction efficiency and damage-threshold for the wide area of the depth to period ratio. It is shown, that the high efficiency diffraction grating with high damage-threshold may be produced. This problem may be resolved by using of relatively deep holographic gratings with multi-layered dielectric coating and by using of different thickness of dielectric layers in different pares of layers.
