在无光阑近场扫描光学显微镜的金属探针针尖上施加针尖增强电场，用于三阶非线性光学过程--相干反斯托克斯拉曼光谱。增强场和三阶非线性的组合解决了嵌入脱氧核糖核酸双螺旋纳米晶体中的腺嘌呤分子的分子振动，超出了光的衍射极限。(C)2004年，美国物理学会。
A tip-enhanced electric field at a metallic probe tip of apertureless near-field scanning optical microscope was applied to a third-order nonlinear optical process, coherent anti-Stokes Raman spectroscopy. The combination of the enhanced field and third-order nonlinearity resolved molecular vibrations of adenine molecules embedded in deoxyribonucleic acid double-helix nanocrystals beyond the diffraction limit of light.
