Linewidth of a Two-Photon Micromaser
The two-photon micromaser provides a clean setup to study two-photon processes. A two-photon lnicromaser was experimentally demonstrated by Brune et at.  by using a. Niobium superconducting cavity. In this paper, we extended the quantum theory of the two-photon lnicromaser developed by Ashraf, Gea- Banacloche, and Zubairy  to study the linewidth by using an ansatz method . We consider a three-level atomic system interacting with a single mode of radiation field inside a cavity with the intermediate level detuned from the cavity mode. We compare the results, under the large detuning limit, with those obtained from an effective Hamiltonian approach.
