Author Affiliations +
In the present paper we consider hologram parameters required to obtain highly selective holographic spectral filters operating in near IR range of spectrum. The properties of photopolymer with diffusion amplification as a medium for recording of narrowband spectral filters for near IR, namely the dispersion dependence of refractive index variations in a wide spectral range, and its influence on the resulting parameters of the holographic filter are analyzed. The experimental result on the recording of a filter optimized for operation at 1.06 micrometers and a combined filter for visible and near IR are discussed.
