We formalize the theoretical effects of optical resonator enhancement on diffraction efficiency, read rate, and write rate of plane wave holograms, with a view toward page based holographic data storage. Trade-offs in cavity enhancement are also examined. Theory predicts ~160% of enhancement in diffraction efficiency is feasible when power loss of the hologram is ~8% and diffraction efficiency is ~8%. We report experimental verification of ~30% enhancement of diffraction efficiency for a hologram written in 0.03% Fe:LiNbO3 (Deltronic Crystal Industries, Inc.) with a 532 nm wavelength, pulsed, DPSS, Nd-YAG, laser and read by a red He-Ne laser. The Bragg selectivity width under the cavityenhanced readout is experimentally confirmed to be unaffected by cavity enhancement, and it agrees with theoretical prediction.
