四能级原子系统中的电磁诱导透明性 (EIT) 可抑制线性吸收，并导致低光强度下共振增强的慢光四波混合。我们分析了EIT条件下四能级系统中的后向四波混频，推导了四波混频效率并讨论了慢光传播条件。我们提出了冷铷原子中逆向方案的共振四波混频的实验测量，并将实验结果与理论计算进行了比较。
Electromagnetically induced transparency (EIT) in a four-level atomic system suppresses linear absorption and leads to resonantly enhanced slow-light four-wave mixing at low light intensities. We analyse the backward four-wave mixing in the four-level system under the EIT conditions, derive the four-wave-mixing efficiency and discuss slow-light propagation conditions. We present experimental measurements of resonant four-wave mixing with the backward scheme in cold Rb atoms and compare the experimental results with the theoretical calculations.
