Abstract

Biphoton holographic storage recorded with 633-nm He–Ne beams has been investigated in Methyl Yellow-doped polystyrene film sensitized by weak noncoherent light from a low-pressure Hg lamp. It is demonstrated that the holography in the sample is erasable without fading. The dynamic behavior of the hologram is dependent on the cis–trans isomerization by noncoherent light and 633-nm beams and photoinduced heat.
