|Title:||Holographic Phase-shift Measurement During Development Of A Fixed Grating In Lithium Niobate Crystals.|
|Author:||de Oliveira, Ivan|
|Abstract:||We report what is believed to be the first direct measurement of the grating phase-shift evolution during white-light illumination for the development of a fixed grating in an Fe-doped lithium niobate crystal. Stabilized holographic recording is shown to be essential for such measurements. Experimental data are in good agreement with theory and allow computation of the relevant material parameters for the sample under analysis. The results are of the utmost relevance for understanding the advantageous behavior of oxidized samples in hologram fixing.|
