这里报道的是向列液晶 (LC) 乳液的相干（共振）随机激光流体。它是一种像普通液体一样的低粘度流体。相干激光是由于液晶液滴密度高（约32%）和液晶折射率高而被开发出来的。 LC 液滴之间形成光学环路，其长度估计约为 150 µm。液晶乳剂对于研究随机激光的机理非常有用，因为它是一种流体，可以很容易地用来改变散射体密度。
Reported here is a coherent (resonant) random laser fluid of nematic liquid crystal (LC) emulsions. It is a low-viscosity fluid like a usual liquid. The coherent laser is developed because of the high LC droplet density (about 32%) and the high refractive index of the LC. The optical loop forms among the LC droplets and its length is evaluated to be approximately 150 µm. The LC emulsion is useful for the investigation of the mechanism of the random laser because it is a fluid and can easily be used to change the scatterer density.
