用探测器原子和空间关联函数测定光谱的比较

Comparisons of spectra determined using detector atoms and spatial correlation functions

Martti Havukainen

摘要:

我们展示了如何两个层次的原子可以用来确定当地的时间依赖的光谱。该方法适用于一维空腔。所获得的频谱与使用空间滤波的二阶关联函数确定的模式频谱进行比较。用二能级原子得到的谱与模谱的结果完全一致。该方法的一个优点是只需要一个时间平均值。它也比时间相关光谱的任何其他定义更接近于现实的测量方案。

英文摘要:

We show how two level atoms can be used to determine the local time dependent spectrum. The method is applied to a one dimensional cavity. The spectrum obtained is compared with the mode spectrum determined using spatially filtered second order correlation functions. The spectra obtained using two level atoms give identical results with the mode spectrum. One benefit of the method is that only one time averages are needed. It is also more closely related to a realistic measurement scheme than any other definition of a time dependent spectrum.
