Laminated holographic recording medium based on photorefractive crystals

A laminated holographic recording medium based on photorefractive lithium niobate crystal is reported for the first time. The medium consists of a piece of photorefractive crystal, a data tracking layer, an intermediate dichroic mirror layer and an anti-reflection layer. Such a holographic medium is able to perform hologram recording and retrieving with compatibility with collinear and coaxial holographic recording schemes.
