Low threshold, frequency-upconverted lasing in the two-photon absorption regime was observed in hexa gonal ZnO nanodisks. Upon near-IR excitation, the ZnO nanodisk resonators produced UV laser emission with a remarkably low threshold $(\sim 1\mathrm{mJ}∕{\mathrm{cm}}^2)$ as well as a resolved lasing linewidth of $\sim 0.1\mathrm{nm}$ . 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.
