Abstract

In this paper a Cu:Fe:LiNbO 3 crystal is chosen to be the recording material with the gating light of 355 nm pulsed laser and the writing light of 633 nm He-Ne laser. We investigate the effect of the pulsed UV pre-exposure on the writing time constant, the achieved maximum refractive-index modulation and writing sensitivity of the crystal.

Abstract

We have investigated the characteristics of thermal fixing holograms in batch. The loss of signal-to-noise ratio (LSNR) is used in comparing the noise performance of hologram before and after each batch of thermal fixing. The experiment results on batch fixing show that the deterioration in hologram fidelity is mainly caused in recording phase at the room temperature, and the repeated fixing processes won't further produce significant noise to degrade holograms.
