Abstract :
In this report, we discussed the interference phenomenon of the AC Stark effect in optical frequency standard with Ramsey spectroscopy. The analytic expression and its numerical result show that an interference fringe is superimposed on the usual AC Stark level shift dispersion line-shape. This phenomenon has never been observed before. By numerical method, we have analyzed the interesting feature of this effect in detail. A method to measure the interference of the AC Stark effect is presented. Finally, a method to observe super-steep dispersion in separated fields scheme is proposed
