摘要：

In this paper a method to obtain very high diffraction efficiency fixed holograms in lithium niobate is presented. The procedure consists in a first step of high temperature recording and fixing of a hologram with very high refractive index modulation, followed by a second step of controlled thermal erasure until the point of maximum diffraction efficiency is achieved.
