摘要
We propose a four-level atomic system with a closed interaction contour connected by two coupled laser fields and a microwave laser field. The transition driven by the probe laser field is outside of the closed interaction contour. In such a system, we mainly discuss the variation of the frequency intervals of double-EIT due to the effect of the closed interaction phase and the strengths of applied laser fields.
