In the Young's double slit experiment, the spatial shift of the interference pattern projected onto a screen is directly related to the phase difference between the fields diffracted by the two slits. We apply this property to fields emitted by nonlinear processes and thus demonstrate background-free coherent anti-Stokes Raman scattering microscopy near an axial interface between a resonant and a nonresonant medium. This method is relevant to remove the nonresonant background in other coherent resonant processes.
在杨氏双缝实验中，投射到屏幕上的干涉图案的空间位移与两个狭缝衍射的场之间的相位差直接相关。我们将这一特性应用于非线性过程产生的场，从而在共振和非共振介质之间的轴向界面附近演示了无背景相干反斯托克斯拉曼散射显微镜。这种方法与去除其他相干共振过程中的非共振背景有关。
