Ying, M. Li, L. Tao, L. Jie, J.Y. Zhou] Optical-field-induced reorientation of 5CB doped with a 1% volume fraction of FeTPPCl (5,10,15,20-tetraphenylporphineiron(III) chloride) were studied. When excited by Ti:sapphire laser with an 82MHz repetition rate and a 80fs pulse duration, the reorientation threshold occurred at an intensity level of 1mW/mm2 for the resonant absorption region, in contrast to the 115mW/mm2 value for the transparent region. A guest resonant model is proposed to explain this anomalous phenomenon: when excited by absorbing light, the FeTPPCl molecule produces an intense resonance absorption which induces a very large dielectric anisotropy, and this therefore enhances the reorientation of the doped system. This phenomenon is very useful for using the liquid crystal as a nonlinear optical component. Springer-Verlag, 2006 Ying X.
