摘要：
We propose a new approach for light induced chiral surface reliefs, in which multiple-armed chiral surface reliefs are formed in an azo-polymer film by the irradiation of the temporally rotating petal beams without orbital angular momentum (OAM). This approach offers new fundamental physical insight of light matter interaction, and it might open the door towards advanced ultrahigh density rewritable optical data storages.
