论文摘要
从开发新的非经典光源的角度来看，非线性光学过程的量化描述可能与之相关。作为一种特殊情况，表征经典驱动系统发出的光很有用，因为在许多实际情况下的激发是激光束。作为物质模型，我们选择了一个两级系统。在较早的工作中，我们研究了光子统计和模式互相关物理。 Rev. A 104（3）：033703，（2021），并指出挤压主要存在于特定参数集中，对应于超摩曼线的退化。在这里，我们专注于这组特定的参数，介绍了挤压的详细信息。
Quantized descriptions of nonlinear-optical processes can be relevant from the perspective of developing novel nonclassical sources of light. As a special case, it is useful to characterize light emitted by classically driven systems, since the excitations in many practical cases are laser beams. As a material model, we choose a two-level system. In an earlier work, we investigated photon statistics and intermodal cross-correlations Phys. Rev. A 104(3):033703, (2021), and noted that squeezing is primarily present in specific sets of parameters, corresponding to the degeneracy of hyper-Raman lines. Here we focus on this specific set of parameters, presenting details of the squeezing.
