System measure for persistence in holographic recording and application to singly-doped and doubly-doped lithium niobate

We define a measure for persistence in holographic recording. Using this measure and the known measures for dynamic range and sensitivity, we compare the performance of singly-doped and doubly-doped LiNbO3 crystals. We show that the range of performance that can be obtained using doubly-doped crystals is much larger than that obtained using singly-doped ones. (C) 2001 Optical Society of America.
