Abstract
We investigated the recording-erase processes of a hologram in photochromic glass using a continuum Nd:YVO4 laser radiation (λ=532nm). Its dynamic was evaluated in the reconstruction step. A bidimensional micrograting pattern was formed and visualized in photochromic glass. In the reconstruction step, we monitored the time decay of the diffraction efficiencyin plane oh the reconstructed object image. It gave information about the processes induced inside the material. Recording and reconstruction processes were done in an off-axis setup, and the movies of the reconstructed object images were recorded on a CCD camera. Measurements from the reconstruction kinetic, gave us information used to computing the variation of the refractive index of the photochromic glass during these processes.
