We have measured the intensity fluctuations of pump and probe beams after interaction with atoms in a situation of Electromagnetically Induced Transparency. Both fields present super-Poissonian statistics and their intensities become correlated, in good qualitative agreement with theoretical predictions in which both fields are treated quantum-mechanically. The intensity correlations measured are a first step towards the observation of entanglement between the fields.
