Abstract
The performance of two-center holographic recording is theoretically studied and described in detail. We present a systematic method for global optimization of two-center holographic recording. Whereas the method presented is general, we perform optimization for lithium niobate crystals doped with iron and manganese Both dynamic range and sensitivity (S) are considered for global optimization, and the optimum design parameters for crystals are predicted. To achieve optimization we use both an analytic approach and a complete numerical approach. The absorption of light in the crystal is also considered. We show that the optimum design parameters for maximizing are different from those for maximizing S. Therefore a trade-off exists between dynamic range and sensitivity. We also describe the complete dependence of S in two-center recording on the design parameters. We show in particular, for the first time to our knowledge, that S depends on the ratio of recording and sensitizing intensities and not on the absolute intensities.
