The reported method allows the recording of volume holographic diffraction gratings in samples of similar to 500 mu m thickness with a high optical quality and low scattering. Holographic grating recording is performed in a single coherent light exposure step, resulting in volume gratings of high optical quality. A holographic notch filter implemented in a 500 mu m thick photopolymerizable glass with a spectral bandwidth below 0.3 nm and an excellent filter extinction ratio of <-27 dB is also demonstrated.engjournal articlehttp://dx.doi.org/10.1063/1.4775787http://scitation.aip.org/open access535Raman-SpectroscopyPattern-RecognitionGratingsStorageÓptica (Física)2209.19 Óptica Física
