Abstract

The diffraction efficiency of M holograms superimposed in the volume of the recording medium is proportional to 1/M2. We present a method, based on nondestructive localized holograms in a doubly doped LiNbO3 crystal, that allows us to also record M holograms in the same volume without an exposure schedule or a diffraction efficiency that has 1/M dependence. We compare experimentally the final diffraction efficiency obtained with the localized and distributed recording methods.

Recording setup. The half-wave plate positioned before the polarizing beam splitter (PB) distributes the power between the reference and the signal beams. The wave plate is mounted upon a rotation stage for continuous power distribution.

Recording curves of a localized hologram. The longer curve is recorded with equal intensities in the reference and the signal beams Ir=Is=11.6 mW/cm2. The other curve is recorded with equal power Pr=Ps=3.1 mW. The reference beam is focused to a lateral extension of 500 µm, and the signal beam is a plane wave of 8-mm diameter.
