Abstract

We develop a theory of quantum fluctuations in lasers which, for the first time, does not rely on adiabatic elimination of the atoms. This allows us to describe different types of lasers which are characterized by different relations between atomic and field spectral widths. We allow for the pumping statistics of the laser medium to vary from Poissonian to perfectly regular. As known, the regular pumping can give rise to reduction of the shot noise, when one photodetects the outgoing laser radiation. The aim of this theory is to compare different classes of lasers from the point of view of quantum fluctuations. This will help to choose the most suitable scheme for the future experiments.
