Single-photon and three-photon absorption induced whispering-gallery mode lasing in ZnO micronails
چکیده انگلیسی

The ZnO micronails were synthesized by the vapor phase transport method. The heads of the micronails show hexagonal disk structure which is suitable for the whispering-gallery mode lasing microcavity. Under the excitation of a nanosecond pulse at 355 nm, the single-photon absorption induced lasing was stimulated in the micronail with the head diameter of 3.0 μm, the whispering gallery mode and Fabry-Pérot mode lasing were investigated. Under the excitation of femtosecond laser pulses at 804 nm, the second harmonic generation and the three-photon absorption induced photoluminescence were observed from a bulk of micronails, then an individual micronail with the diameter of 9.1 μm was employed to realize the three-photon absorption induced whispering-gallery mode lasing.
