Abstract :
Reported here is a coherent (resonant) random laser fluid of nematic liquid crystal (LC) emulsion in water. It is a low viscosity fluid like a usual liquid. The optical loop forms among the LC droplets and its length is evaluated to be approximately 150 micrometers. The LC emulsion is useful for the investigation of the mechanism of the random laser because it is a fluid and easy to change the scatterer density.
