We present the theory of a truly microscopic maser, and show that it exhibits novel features not associated with masers and lasers generally. In particular, it usually does not produce coherent radiation. The coherence of the field in conventional masers and lasers originates from incoherent averages which smear out quantum details of the field-matter interaction.
