用一种新的干涉法测量了主客体液晶的复光热折射率变化。复折射率的变化与泵浦光强度成正比。真实的部分的绝对值大约是虚部分的十倍。非寻常折射率变化的绝对值约为寻常折射率变化的9倍。非寻常折射率变化的真实的部分为负，寻常折射率变化的虚部为正，非寻常折射率变化的虚部和寻常折射率变化的虚部均为负。这些结果可以用主客体液晶和染料的光热效应来解释。
A complex photothermal refractive index change in host-guest liquid crystals was determined with a novel interferometric method. The complex refractive index change was proportional to the pump beam intensity. The absolute value of the real part was about ten times as large as that of the imaginary one. The absolute value of the extraordinary refractive index change was about nine times as large as that of the ordinary one. The real part of the extraordinary refractive index change was negative, while that of the ordinary one was positive, and the imaginary part of both the extraordinary and ordinary refractive index change was negative. These results can be explained by the photothermal effects in the host-guest liquid crystals and dyes.
