Abstract

We analyze and compare two typical recording and thermal fixing procedures of a volume hologram in a Fe:LiNbO3 crystal (low–high–low procedure and high–low procedure). We consider the kinetics of the recording, compensating, and developing processes by taking into account the ratio of the conductivities between the protons and the electrons as a function of temperature. From the analysis the optimal environmental conditions (in terms of the fixing temperature and the compensation time) for each fixing procedure can be deduced for a crystal with given material parameters.
