在相干外场作用下的V型三能级原子对探测光吸收性质的研究

Study on Probe Absorption Properties in a V-type Three-level Atomic System Driven by Coherent Field

采用一个相干外场作用到V型三能级原子系统的激发态与另一个激发态构成的跃迁上,发现该外加相干光场对该原子气体吸收性质有很大的影响,当该光场的强度在一定范围内时,探测光会被放大.

In this paper, an external coherent field is used to perform a transition between an excited level and another one within a V-scheme three-level atomic system. It is found that the atomic optical properties can be affected by the coherent field, and the probe light can be magnified when the coherent field is strengthened to a certain extent.
