Abstract

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.
