Abstract

Emission spectra of a pair of effective two-level atoms interacting with two modes of the cavity field through Raman interaction are studied, where the interaction of each atom with the field may be different. The spectra with two modes of the cavity field being initially in various number states are analysed in detail. It is found that emission spectra manifest following new properties: When mode 1 of the cavity field is in vacuum state and the other is in the weak field , the spectrum shows symmetric ten peaks and six peaks alternately, with the increase of R=g2/g1, which reflects the different Raman interacting intensities of two atoms with the cavity field more sensitively compared with the spectrum of two atoms in a single-mode cavity. The spectrum with 01=1, n2=50 and n1 = 50, n2=1 reflects the different positions of mode 1 and mode 2 of cavity field interacting with two atoms through Raman process. Finally, the symmetric 16-peaks structure of the spectrum is explained.

CAVITY FIELD SPECTRA OF AN ATOM INTERACTING WITH TWO-MODE FIELD THROUGH RAMAN PROCESS

The cavity field spectra of a two level atom interacting with two mode field through Raman process are investigated. It is shown that the basic features of the spectra is unchanged whether the atom is in the high or low level state initially. Symmetrical two peak structure appears in the spectrum for each mode when the initial fields are both in the pure number states or both in the coherent states. The split of the two peaks is proportional to the field intensity of the other mode.

Cavity Field Spectra of Two Different Atoms Interacting with Two-mode Field

Guiming Zhang, Gao Yun-feng

The cavity field spectrum of two atoms interacting with two-mode fields with different coupling constants(g_1≠g_2) was studied.By solving the eigen equation,the cavity field spectrum expression of the system was given out.Some numerical results for the fields in pure number state and the atoms in the upper level were presented initially.The effects of the relative coupling constant R=g_2/g_1 or photon number on the spectrum structure were analyzed.It is found that R plays a different role in the spectrum with field in vacuum state,weak state and strong state.The frequency of one mode field spectrum is tuned by the intensity of the other mode.The frequencies of two modes spectra can be changed by the relative coupling constant.

Emission spectrum of two atoms interacting with two modes of the cavity field with different coupling constants through a multiphoton Raman process

Jian Feng, Song Tong-Qiang, Gao Yun-feng

The emission spectrum of a pair of effective two-level atoms interacting with two modes of the radiation field with different coupling constants through a multiphoton Raman process is studied. A general expression for the emission spectrum with two modes of the field being in arbitrary states is presented. Our results show that when two modes of the field are in arbitrary number states, the spectrum is always symmetric about the resonant frequency , although the Hamiltonian of the system is asymmetric which is induced by the two different atom-field coupling constants. This property is analysed with an analytic method.

Cavity field spectrum of two coupled atoms Raman interacting with single mode field

Yun Liang Gao

The cavity field spectrum of two coupled atoms Raman interacting with a simgle mode field in an ideal cavity is investigated. The effects of dipole dipole interaction of atoms and exchange symmetry of the initial state of atoms on the cavity field spectra are analyzed. It is found that five peak structure appears for weak fields, and three peak structure appears for strong field. When the two atoms are in the different state initially, the exchange symmetry of the atoms play a decisive role in the structure of the cavity field spectra.

Influence of AC-Stark shift on cavity field spectra in the non-degenerate Raman process

Gao Yun-feng, Feng Jian, (1)聊城大学光通信研究所，聊城 252059;中国科学院武汉物理与数学研究所波谱与原子分子物理国家重点实验室，武汉 430071; (2)聊城大学教育技术系，聊城 252059

The cavity field spectrum of an atom interacting with two-mode field through non-degenerate Raman coupling with the presence of AC-Stark shift in an ideal cavity is investigated. The results for the atom in the low-level state and the initial fields in pure number states, coherent states, and squeezed vacuum states are calculated. When the initial fields are in number states, the three-peak structure of each model cavity field spectra appear for weak fields, and two-peak or single-peak structure appear for strong fields. When both field modes are in a superposition of number states initially, the cavity field spectra are generally of two-peak structure. With the increase of γ=g2/g1,one peak rises and the other peak reduces.
