Advanced Functional Materials, EarlyView.Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.
