Fe2O3超微粒溶胶的光学非线性研究
Study on Nonlinear Optical Properties of Ferric Oxide UFP Sol
【摘要】 本文采用了四波混频(DFWM)手段首次研究Fe2O3水/有机溶胶的三阶非线性光学特性.有机溶胶显示了较大的非线性极化率X3.最后讨论了Fe2O3超微粒的三阶非线性的产生机制.
【Abstract】 A study on the third order nonlinear optical properties of ferric oxide UFP hydrosol andorganosol was carried out with the Degenerate Four Wave Mixing (DFWM) technique. Or-ganosol exhibits higher nonlinear susceptibility X3 compared to the hydrosol. The X3 gener-ation mechanism of Ferric oxide UFP sol is also discussed.
