Xiangping Li et al. demonstrated write-once holograms for wide-angle and full-colour three-dimensional images using subwavelength-scale pulsed femtosecond laser reduction of graphene oxide to enable multilevel optical index modulation and restoration of vectorial wavefronts of polarization discernible images through the vectorial diffraction of a reconstruction beam.
