The record of diffraction gratings in the material composed by Norland 65 (polymer) mixed with crystal violet; describe changes in its diffraction efficiency that it shows the material when is exposed to times of exposition extended, since 1 min to 3 hours, due to phase modulation change. They recorded the diffraction gratings in real time to an angle of interference of 5°, utilizing He-Ne laser with 598 nm (yellow color), with efficiencies of diffraction η (%) between 0.71 and 2.10 % only in the order 1.
