Abstract: | In quantum optics, some models are considered to
describe many aspects of the dynamics of atoms coupled to an
electromagnetic field (laser). The simplest atomic model is of
course the two-level-atom which is governed by the Bloch optical
equations. In general this system is solved in the steady state or
by using some approximations. An extended analytic approach is
considered for this coupled equations. The separation approach of
coupled differential equations is always possible with a sequence
of special transformation into nonlinear differential equations.
The conditions that permit an exact solution of three coupled
systems are extracted in a natural manner. The case of sodium atom
moving along the axis of a standing-wave is investigated in some
details. |
