摘要
A method of 3D holographic recording by using a very simple optical system includes dividing a femto-second laser pulse into a plurality of light beams by a diffraction beam splitter, focusing four light beams selected from the divided plurality of light beams, controlling each optical phase of the selected four light beams by a phase retarder, and further focusing these four light beams into a sample comprised of a photosensitive material capable of multi-photon exposure so that the photosensitive material is exposed to the interference among the four light beams and multi-photon absorption in the sample is induced, thus recording a 3D phase hologram on the irradiated portion of the sample.
