摘要：

A simple photopolymerizable dry polymeric film based on pyrromethene dye (PM567) which it has been usually used in solid-state dye lasers, has been developed. This new composition is based on only three components: poly-(methylmethacrylate) (PMMA) as a binder, 2-hydroxyethylmethacrylate (HEMA) as a monomer and 1,3,5,7,8-pentamethyl-2,6-diethylpyrromethene-difluoroborate (PM567) as photoinitiator. Diffraction efficiencies near 60% are obtained with exposures of approximate to1 J/cm(2) in materials of 500 mum of thickness. We have studied the holographic properties of the material when the concentration of monomer and intensity are changed, obtaining good results at low intensities, which it implies that this material can be used in applications based on low power lasers.
