On-demand assembly of optically levitated nanoparticle arrays in vacuum
Fig. 1. Experimental setup and image of an optically levitated nanoparticle array. (a) The 2D trap array is produced by passing a 1064 nm laser through a pair of orthogonal acousto-optic deflectors (AODs). The laser beams created by the AODs are imaged with a 4f image system onto a high NA (
