17 March 2000 Highly selective holographic spectral filters for near IR range
Author Affiliations +
In the present paper we consider the possibility to obtain highly selective holographic spectral filters operating in near IR range of spectrum. The properties of photopolymer with diffusive amplification as a medium for recording of such filters are analyzed, namely the mechanism of diffusion enhancement of hologram diffraction efficiency, the dispersion dependence of refractive index variations in a wide spectral range, and its influence on the resulting parameters of the holographic filter. The experimental results on the recording of filters optimized for operation at particular wavelengths of 0.85, 1.06 and 1.5 micrometers are presented.
