Abstract
Holographic gratings have been recorded in additively and electrolytic ally coloured KBr crystals at wavelengths of 514.5 and 632.8 nm respec tively. The storage properties of additively coloured crystals have be en investigated for 7 years. It has been proved that the storage times less than 4 years are reasonable. It has also been verified that temp erature changes during the recording process are the main reason for l ow diffraction efficiencies. Finally the influence of the relaxational self-enhancement of the diffraction efficiency on the storage propert ies of these crystals has been studied.
