Paper Abstract

We recorded real time holographic gratings in a photosensitive liquid material. This material is Norland Optical Adhesive (NOA 65(R) ) mixed with crystal violet dye (CV). The NOA 65(R) is a clear, colorless, liquid photopolymer that cures when is exposed to ultraviolet light (UV) but when is mixed with crystal violet becomes sensitive to visible region of the electromagnetic spectrum. To record the gratings we used the interference between two beams from a He-Ne, obtaining phase modulation gratings by refraction index changes. We use three different wavelength, λ = 633 nm, 612 nm and 594 nm for recording the gratings and its highest diffraction efficient was obtained when the grating was illuminated with a wavelength λ= 594 nm whose value was of 10.76 %. This mixture of NOA 65(R) and CV open the possibility to make diffractive elements.
