实验中研究了不同盒厚(100μm、188μm、300μm)及摩擦取向(双面平行、双面反向、双面垂直)的液晶盒在温度变化下出射随机激光的特性。实验结果表明，随着温度的升高，随机激光的强度降低直至完全消失，继续升温随机激光重新出现。样品表面摩擦取向也会影响染料掺液晶随机激光的温控特性，同向摩擦的液晶盒随机激光消失点温度值较低。因此可以通过改变样品表面摩擦取向将随机激光阈值设置在特定的温度，可应用于远程温度传感领域。

We experiment with liquid crystal cells which have different thicknesses(100 μm,188 μm,300 μm) and different orientations ( parallel, reverse, vertical ) and analyze their physical mechanism. The experimental results show that when the temperature increases, the intensity of the random laser reduces to zero. The random laser reoccurs at higher temperature. Parameters of the cell, such as orientation, will make difference to the thermal behavior of random laser. The random laser disappears at lower temperature when the cell has parallel orientation. Therefore the threshold behaviour of random lasers can be set to specific temperatures. This laser may find application in remote temperature sensing.
