Optimisation and coupling of high-performance photocyclic initiating systems for efficient holographic materials
Résumé
To enhance the efficiency of photopolymerizable systems as holographic recording materials, acceleration of the curing rate by 3-component photoinitiating systems (PIS) was turned to account. The study was based on gratings’ recording. The photochemistry of 3-component PIS also impact the hologram formation and the result is the design of a material giving rise to thick phase holograms with both high diffraction yield and high rate of formation was not straightforward.
