采用气相传输法制备了具有六边形横截面的纤锌矿结构ZnO微针，并采用单个微针作为激光微腔。在800 nm波长的飞秒脉冲激光激发下，获得了窄线宽、高Q值的紫外（UV）激光发射。详细讨论了紫外发射、谐振机制和激光模式特性。结果表明，紫外激光源自拉比振荡辅助的双光子吸收引起的回音壁模式。
Wurtzite structural ZnO microneedles with hexagonal cross section were fabricated by vapor-phase transport method and an individual microneedle was employed as a lasing microcavity. Under excitation of a femtosecond pulse laser with 800 nm wavelength, the ultraviolet (UV) laser emission was obtained, which presented narrow linewidth and high Q value. The UV emission, resonant mechanism, and laser mode characteristics were discussed in detail. The results demonstrated that the UV laser originated from the whispering-gallery mode induced by two-photon absorption assisted by Rabi oscillation.
