摘要：
A four-level inverted-Y configuration driven by two control fields is considered to demonstrate the phenomenon of electromagnetically induced transparency (EIT). It is shown that the double EIT can be realized in this system. Such double transparency spectra can be locally modulated by changing the detunings as well as the Rabi frequencies of the control fields.
