A master equation for the light, generated by atoms, which states are prepared by a pumping mechanism produced the atomic correlation, is derived in the Fokker-Planck approximation. It has been found, that two-particle correlations play only the role under this approximation. The obtained equation can describe a micromaser operations, which the light noise is discussed for example. We consider ...

We develop a Radon like transformation, in which P quasiprobability distribution for spin 1/2 states is written in terms of the tomographic probability distribution w.

Focusing of atoms with light potentials is studied. In particular, we consider strongly confined, cylindrical symmetric potential, and demonstrate their applications in both red and blue-detuned focusing of atoms. We also study the influence of aberrations, and find that a resolution of 1 nm should in principle be possible.
