Phase-coded time-domain holography in persistent hole burning materials

摘要

The possible application of the spectral hole burning in the optical storage field has attracted scientists' attention due to its high density storage which increases 3 orders of magnitude more than that of the present conventional optical disk. By adding a frequency space to the optical storage the storage density can break through the limitation exerted by the light spot diffraction in the three-dimensional space. The holographically optical storage by using the persistent hole burning media has been proved to be promising in the application of the processing and the storing of ultrafast optical information.
