Paper Abstract

Results of investigations of diffraction efficiency (DE) temperature dependence and optical damage threshold of volume phase holograms-transmission gratings are presented. DE remains constant in the range +10 < T < +110 degree(s)C for holograms on the base of PPC-488. Changes of DE are reversible in +110 < T < +200 degree(s)C and if T > +200 degree(s)C the irreversible change takes place because of specific cracking of films along phase planes. The reversible change of DE can be described by diagrams of phase balance in the system: polymer-diffusant. Optical damage threshold of under study gratings is defined by the threshold of photo- and thermo-decay of neutral diffusant 1-naphthalene bromide. Different compositions, which contain the diffusant with high threshold of photo- and thermal-dissociation processes have been tested. Some modifications of basic photopolymer composition with the threshold of optical damage more than 200 MW/sm2 were proposed.
