The second hologram is then copied into a third holographic recording medium substrate to provide the final copy hologram.

Abstract: The present invention concerns the use of hybrid metal-dielectric optical coatings as the end reflectors of laser cavities and/or in the mirror structures used in other optical resonators, such as Fabry-Perot tunable filters, along with the use of such Fabry-Perot tunable filters in wavelength swept sources such as lasers. Hybrid metal-dielectric optical coatings have reflectivity spectra that can be broader than pure dielectric coatings, offer optical reflectivities higher than metal, as high as pure dielectric coatings, eliminate mirror transmission that can cause parasitic light reflections, and use fewer layers and thus have lower mass and higher mechanical resonant frequency for movable mirror applications An important characteristic of these coatings concerns the non-reflected light. Pure dielectric coatings offer high reflectivity, while the non-reflected portion of the light is transmitted by the coating to the substrate, for example.
