摘要：

Diffraction properties of both transmission and reflection volume gratings written in wave-coupling materials are analyzed based on the concept of mean fringe contrast of the interference pattern formed in the recording process. Optimum beam ratio and corresponding maximum diffraction efficiency are derived. This shows that the lossless transmission and reflection gratings have very similar diffraction behaviors. Experimental results for reflection gratings are also presented.
