  We demonstrate that the transport of coherent quasiresonant light through a
dense cloud of immobile two-level atoms subjected to a static external electric
field can be described by a simple diffusion process up to atomic number
densities of the order of at least $10^2$ atoms per wavelength cubed. Transport
mean free paths well below the wavelength of light in the free space can be
reached without inducing any sign of Anderson localization of light or of any
other mechanism of breakdown of diffusion.
