We examine coherence properties of small-area, intrinsically stationary statistical pulses propagating in amplifying media in the vicinity of an optical resonance. Any such medium acts as a coherent linear amplifier, amplifying and reshaping the pulse. We show that an initially nearly incoherent Gaussian Schell-model pulse becomes almost fully coherent and its state of coherence becomes nearly uniform across the temporal profile as the pulse propagates into the amplifying medium.
