We propose and experimentally demonstrate a method that is capable of resolving both real and imaginary parts of third-order nonlinearity (χ(3)) in the vicinity of Raman resonances. Dispersion of χ(3) can be obtained from a medium probed within microscopic volumes with a spectral resolution of better than 0.10 cm(-1).
我们提出并实验证明了一种方法，能够在拉曼共振附近分辨三阶非线性（χ(3)）的实部和虚部。可以从具有优于 0.10 cm(-1) 的光谱分辨率的微观体积内探测到的介质中获得 χ(3) 的色散。
