A new spectroscopic technique for studying adsorption of atoms at a transparent dielectric surface is exploited. A quantitative comparison of the Autler-Townes splitting in measured and calculated, surface temperature-dependent two-photon evanescent wave spectra provides values of the adsorption energy, the preexponential factor for the rate of desorption and the polarizability of alkali atoms, adsorbed on a glass surface. It is speculated that this technique could form the basis for future two-photon control of atoms close to dielectric surfaces.
人们利用一种新的光谱技术来研究原子在透明介电表面的吸附情况。通过对测量所得和计算所得的、与表面温度相关的双光子倏逝波光光谱中的奥特勒-汤斯分裂进行定量比较，可得出吸附在玻璃表面的碱金属原子的吸附能、解吸速率的指前因子以及极化率的值。据推测，该技术可能为未来对靠近介电表面的原子进行双光子控制奠定基础。
