Paper Abstract

The formation of holographic gratings in an azo-glass is investigated for the simple case of an intensity grating in the s-polarization of the recording beams. A dual grating is formed as a function of time with a refractive index grating and a relief grating. The diffraction efficiency as a function of recording time is discussed in a model of 2 consecutive processes with a phase shift. A material transport process is involved in the formation of relief patterns. A thermal erasure process at the glass transition is compared with an optical process.
