Abstract
It is well known that very thick volume holograms both transmission and reflective type being illuminated by light indicate very high angular (less than milliradian) and spectral (less than nanometer) selectivity. Such highly selective holograms can find wide application in different fields. The variety of diffraction elements: filters, angular and spectral selectors, etc. can be designed basing on very thick holograms. The main problem in manufacturing of thick holograms (of about millimeter thickness) is in developing of very thick photosensitive media, in which this grating can be recorded without shrinkage and distortions. The overview of Russian materials suitable for the recording of thick volume holograms is made in this paper. We demonstrate the experimental results of the recording of high efficient (90%) transmission angular selector (with the selectivity bandwidth of about milliradian) and reflection spectral selector (bandwidth of about nanometer) using PDA material (photopolymer with diffusive amplification). Such very high selective optical elements can find application in spectroscopy, space communication, lidar sensing, wavelength demultiplexing, optical storage, and others.
