摘要： The invention relates to a dispersive optical device with a three-dimensional photonic crystal. The purpose of the invention is to provide a device having as a whole a high damage threshold and that is easy to manufacture while maintaining optimal optical properties. This goal is achieved by using a silica device including a three-dimensional photonic crystal and a diffraction array. The device can particularly be used in a compressor system of a short-pulse laser.

摘要： The present invention relates to an optical reflective diffraction device (100) which has a high diffraction efficiency and a high resistance to laser flux, and which can be easily produced. The device is characterized in that it includes a protective structure (140) including at least one mixture layer (141) prepared by uniformly mixing a first material and a second material, both of which are dielectric, said first material having an optical index that is lower than that of the second material.

摘要： The invention relates to a method for adjusting the pupillary delay compensation of a convergent or divergent beam. The method comprises the steps of placing a device comprising an afocal system with one or more optical passive components arranged on the propagation axis of said beam, wherein one at least of said components is a diffractive focalising component, and displacing the device along the beam propagation axis until the desired pupillary delay compensation is achieved, said compensation being the algebraic sum of the pupillary delays of each passive optical component of the afocal system and being comprised in a range of values whose limits depend on the particular combination of the optical components selected for realising the afocal system of the compensation device.
