Abstract :
The method for investigating the holography time constants in two-center holographic recording is proposed. The effects of the Fe and Mn concentrations, oxidization-reduction state and intensity ratio IR/IUV on the recording time constant and erasure time constant in doubly doped LiNbO3:Fe:Mn crystal are theoretically studied by using the numerical method. The results show that the smaller recording time constant and the larger erasure time constant can be achieved simultaneously by using the lower Mn concentration and the larger intensity ratio IR/IUV in multiplexing holograms.
