Norland Optical Adhesive 72® as phase holographic material

Characterization of the holographic material composed by adhesive polymer Norland Optical Adhesive 72® (NOA 72®) was studied. With a wavelength of 457 nm from an Ar laser, real time phase holographic gratings under different parameters such as energy, frequency and thickness were recorded. The diffraction efficiency of the recorded holographic gratings was measured and some experimental results are shown. Furthermore, the material was used to record Fourier holograms.
