Article Synopsis
- The study focuses on recording volume holograms using 532 nm light in new photopolymer nanocomposites that include hyperbranched polymers (HBPs) to improve performance.
- HBPs have a high refractive index of 1.82 due to their unique molecular structure, allowing for the creation of high-contrast volume holographic gratings.
- These gratings can achieve significant modulation in refractive index (2.2×10(-2)), enabling very efficient (near 100%) diffraction for 10 μm thick holograms in the green light spectrum.
