Diffraction efficiencies and characteristic erasure times were measured for two recording materials suitable for real-time holography and four-wave mixing. A study of real-time transmission volume grating formation was done in conjunction with polarization states of the writing beams for 30-μm thick layers. Modulation transfer function curves presented were obtained using a versatile device for which the spatial frequency domain was 500–4000 cycles/mm.
