Abstract
Highlights Femtosecond-laser allows for high-precision, chemically clean, and repeatable fabrication. Large perovskite single-crystal films improve the microcavity quality. Low-threshold, narrow-linewidth perovskite microlaser arrays are realized. Possibility of the single-mode microlasers for use as pixels is demonstrated.
