We have demonstrated electrical fixing of 1000 angle-multiplexed holog
rams in a 1-cm(3) volume Ce-doped SBN:75 crystal. A revealing procedur
e yielded an average diffraction efficiency of 0.005% for each hologra
m, with approximately 20% variation. The erasure resistance of the fix
ed gratings was verified. (C) 1997 Optical Society of America.
