Atomic Interference in the Micromaser
The aim of the projected research is to theoretically characterize the several mechanism leading to the appearance of atomic interference in the micromaser. A manifestation of atomic interference generated within the micromaser cavity has been recently observed experimentally in Garching, revealing itself as spikes in the maser line.
We plan to develop a theoretical model, to characterize this interference phenomena. Special attention has to be paid to the role of the fine structure of the atomic levels in order to optimize the election of the maser transi- tion. In order to test the analogy of the observed interference pattern with the usual Ramsey fringes, the competition of both intra- and extra-cavity interference mechanism will be investigated. This competition will show up when the micromaser cavity is sandwich between two separated-oscillatory Ramsey fields.
