  • Owing to its electronic and optical properties, graphene holds potential for flat display systems. Here, Li et al. write wide-angle, full-colour, three-dimensional holographic images using subwavelength, multilevel index modulation of athermally reduced graphene oxide by a single femtosecond pulse.

  • The combination of optical phase conjugation and light amplification enables wavefront shaping with simultaneously optimized operational speed, number of control degrees of freedom and energy of the focused wavefront. Shaping with a 10 μs latency time over about 106 control modes and energy gain approaching unity is demonstrated.
