| 摘 要： | 本文中探讨了MBBA液晶中,由热致位相光栅产生的简并四波混频效应。通过测量热光栅衰变的弛豫时间,得到T=45.1℃时,液晶各向同性相的热弥散系数为D=8.6×10-4)cm2·S-1)。

| Abstract: | Degenerate four-wave mixing effect due to thermally induced index grating is studied in liquid crystal MBBA. By measuring the relaxation time of the thermal grating decay, we obtain the diffusion coefficient of MBBA in its isotropic phase, i.e., D=8.6×10-4cm·S-1 at T = 45.1℃. |
