Abstract

We demonstrate for the first time two-photon induced holographic recording at an arbitrary point in three dimensional photopolymeric cube by overlapping two coherent pulses from a 200 femtosecond Ti: Sapphire tunable laser operating at 710 nm. Spatial overlap is achieved by a novel pupil division method. The polymer material is made of epoxy host, which is fully polymerized and filled with liquid photopolymerisable formulation comprising acrylate type monomer and two-photon photoinitiator. Measured diffraction efficiency is measured to be 3.5%.
