Diffraction grating groove density

Webthe creation of diffraction gratings and volume holo-grams in glass ceramics becauseof their unique ther-mal properties [1,2]. Stookey was the first to report photosensitivity in glass-ceramic materials as long ago as 1949 [17]. He demonstrated photoinduced opacity in metal-doped glasses and glass ceramics that were subsequently heated. WebDiffraction Gratings. A diffraction grating is an optical element that diffracts energy into its constituent wavelengths. The groove density, depth and profile of a diffraction grating dictate the spectral range, efficiency, resolution and performance of the diffraction grating. There are typically two different types of diffraction grating ...
