Paper Abstract

Photothermoplastics are shown to have a capacity to record the interference gratings or holograms with spatial frequencies ranging far away the self-rastering frequency. The frequencies is corresponding to the chaotic deformation shifts towards the low-frequency range with the increase of the recording temperature. The recorded holograms with various spatial frequency do not alter the absolute values of self-rastering. The temperature dependence of the square root of the diffraction efficiency shows a maximum at the flow point temperature of the thermoplastic used. As the temperature rises, the coefficient determining the relationship between the resonance frequency and thermoplastic layer thickness increases.
