摘要：
A core-resonance cylindrical whispering gallery mode (WGM) laser is reported in dye-doped nematic liquid crystals (NLCs) filled in a glass capillary. This laser runs on the basis of the properties that NLC has an extraordinary refractive index much higher than that of a glass and that it plays as a good solvent for laser dye. The conditions of the WGM lasing are investigated on the basis of gain and loss of the core medium. The NLC is a material suitable for optofluidic core-resonance cylindrical WGM lasers, which are promising, from an application viewpoint, for biodevices or analytical microdevices.
