We investigate the nonvolatile holographic storage characteristics of near-stoichiometric LiNbO3 :Fe:Mn crystals with different Li2O contents. Experimental results indicate that the optimal value of Li2O content is about 49.6 mol%. Nonvolatile sensitivity S considerably improved to 0.15 cm/J because of the use of near-stoichiometric LiNbO3 :Fe:Mn with 49.6 mol% Li2O.
