Kerr介质中双原子-压缩真空场系统的腔场谱

研究了含Kerr介质腔中耦合双原子间与双模均处于压缩真空态的光场拉曼相互作用过程的腔场谱.通过求解本征方程导出了双模光场处于任意强度时腔场谱的计算公式,给出了数值计算结果.发现在两模初始场均为弱场时,Kerr介质和原子间的耦合作用对谱结构的影响较小;当双模初始场均为强场时,两模主峰的右侧出现了半梳状边峰,随Kerr效应的增强,峰间距逐渐加宽,并向高频方向扩展,在Kerr效应较强时,两模边峰的峰高出现高低相间的现象.

Cavity Field Spectrum of Two Atoms Interacting with Squeezed Vacuum States in Kerr Medium

The cavity field spectra of two coupling atoms interacting with two squeezed vacuum states of field through Raman process in Kerr medium are studied.By solving the eigen equation,the cavity field spectrum expression is given out and some numerical results are presented.It is found that both the Kerr effect and the atoms coupling influence the spectra structures slightly in the case of weak input field.When the input fields are strong,the highest peak at lift with a multi-peak right sideband spectrum like a half comb appears.Along with the accretion of Kerr effect,the peak-space of the sideband increases and the spectral frequency shifts away from the resonant frequency.A multi-peak spectrum checkered with different height appears with the stronger Kerr effect.
