我们观察到从陷波子晶体散射的光的干涉。通过改变激发激光的强度,我们研究了弹性和非弹性散射对条纹图可见度的影响,并将其与离子温度和波包局域化的影响区分开来。通过这种方式,我们确定了由单个原子产生的光场的相干性和相互相干性的复杂程度。我们获得的干涉条纹由两个,三个,和四个离子在一个谐波陷阱的晶体。控制的捕获电位允许调整的原子间的距离,从而形成的线性阵列的原子作为一个规则的光栅的微观散射。
We observe interference in the light scattered from trappedion crystals. By varying the intensity of the excitation laser, we study the influence of elastic and inelastic scattering on the visibility of the fringe pattern and discriminate its effect from that of the ion temperature and wave-packet localization. In this way we determine the complex degree of coherence and the mutual coherence of light fields produced by individual atoms. We obtain interference fringes from crystals consisting of two, three, and four ions in a harmonic trap. Control of the trapping potential allows for the adjustment of the interatomic distances and thus the formation of linear arrays of atoms serving as a regular grating of microscopic scatterers.
