The hexagonal ZnO microrods were employed as whispering gallery mode (WGM) microcavities to obtain ultraviolet laser at room temperature. For each individual ZnO microrod, the laser presented low threshold and high quality Q factor and clear WGM spectral structure. The lasing spectra from different microcavities were combined together by pumping two or more ZnO microrods simultaneously. The resonant process and lasing characteristics, Such as lasing mode, threshold, and Q factor. were investigated in experiment and theory. (C) 2009 American Institute of Physics.
