In their recent study [Phys. Rev. Lett. 88, 143902 (2002)] on a four-wave mixing (FWM) process, Deng et al. state that ‘‘many orders of magnitude enhancement in the amplitude of the generated wave’’ is obtained when electromagnetically induced transparency (EIT) is present. Here we will show that their claim is deeply misleading.
