Down-conversion of high-frequency EM field in a simple quantum two-level system (also known as two-level atom) with broken inversion symmetry driven by a coherent laser field and damped by a squeezed vacuum reservoir is analyzed. It is shown that the squeezing leads to broadening of the low-frequency radiative peak in the fluorescence spectrum of the system. At the same time, changing the reference phase of the squeezed field and the degree of squeezing allows to manipulate the shape of this peak.

压缩真空储能阻尼的量子二能级系统中的电磁场频率下变频

分析了一个简单的量子二能级系统（也称为二能级原子）中高频电磁场的下变频，该系统具有相干激光场驱动并受压缩真空储能器阻尼的反转反转对称性。结果表明，压缩导致系统荧光光谱中低频辐射峰的加宽。同时，改变压缩场的参考相位和压缩程度可以控制该峰的形状。
