Nature, Published online: 30 July 2025; doi:10.1038/d41586-025-02383-3Metalasers have been developed using metasurfaces comprising nanodisks, each with an off-centre hole. By changing the rotation angle of the nanodisks holes, the wavefront of the metalasers emission can be modified to generate arbitrarily shaped beam profiles, including focal spots, vortices and holograms, with notably low levels of speckle noise.
