abstract = {We study large fluctuations of emitted radiation in the
system of N non-interacting two-level atoms. Two methods are
used to calculate the probability of large fluctuations and
the time dependence of excitation and emission. The first
method is based on the large deviation principle for Markov
processes. The second one uses an analogue of the quantum
formalism for classical probability problems.Particularly we
prove that in a large fluctuation limit approximately half
of the atoms are excited. This fact is independent on the
fraction of the excited atoms in equilibrium.},
