| 摘 要： | 研究了在双暗态共振四能级原子系统的基础上,附加一个信号场扰动的五能级原子系统中的探测放大响应。发现仅通过调节信号激光场的强度就能实现探测放大的增强。根据量子干涉理论和缀饰态理论定量地解释了产生该结果的物理机制.

| Abstract: | The paper studies response of the probe amplification in a five-level atomic system disturbed by introducing an additional signal field, which is based on the four-level atomic system with interacting double-dark resonances. It is found that a large enhancement of the probe amplification can be achieved by adjusting the strengths of the signal laser field. From viewpoint of physics, this result in terms of quantum interference and dressed state is explained. |
