Inhomogeneous magnetic fields are limiting the applications of electromagnetically induced transparency like slow light, quantum memory and quantum repeaters. As an optical dipole trap works independent of magnetic fields, we are able to apply a homogeneous field, which enables us to overcome these limitations. We use Rubidium atoms in a CO2-laser dipole trap, which is directly loaded from a magneto-optical trap.
We present EIT measurements with co propagating Raman laser beams showing absorptive and dispersive features with a width less than 10kHz.
