Abstract

Low threshold, frequency-upconverted lasing in the two-photon absorption regime was observed in hexagonal ZnO nanodisks. Upon near-IR excitation, the ZnO nanodisk resonators produced UV laser emission with a remarkably low threshold (∼1 mJ/cm²) as well as a resolved lasing linewidth of ∼0.1 nm. Modal analysis and far-field photoluminescence imaging of the nanolasers have suggested the dominance of whispering-gallery modes in the two-photon pumped microcavity lasing process.
