Storage of 500 high-resolution holograms in a LiNbO(3) crystal

We have recorded (at room temperature) as many as 500 high-resolution, uniformly diffracting volume holograms in a single Fe-doped LiNbO(3) crystal. The holograms were stored by angularly multiplexing a plane-wave reference beam. The graphical procedure that we used to compute exposure schedules is described. Experimental results are also presented.
