✦ Synopsis

We analyze both the spatial as well as the temporal coherence of an electron -hole condensate and the radiation emitted from it. These coherences evolve from being full for the low density Bose -Einstein condensate to a chaotic behavior for a high density Bardeen-Cooper -Schrieffer-like state. Time coherence is transferred, to the emitted radiation in the ultrafast regime, in a damped oscillatory way.
