Master Equation for Light emitted by correlated Atoms
  A master equation for light generated by atoms, which states are prepared by a pumping mechanism that produces atomic correlations, is derived in the Fokker-Planck approximation. It has been found that two-particle correlations only play the role under this approach. Then the equation is applied for describing micromaser operations and light noise is discussed. We consider the correlated atomic states prepared by telecloning protocols.
