On the analytical solution of the optical Bloch equations

We present in this note the analytical solution of the optical Bloch equations for different scenarios of the parameter space. Our method partially follows the reported by H-R. Noh and W. Jhe Opt. Commun. 283, (2010) 2353]. However, it differs substantially with the analytical solution reported by these authors. We use the exact solution provided by numerical standard algorithms as a pattern for comparison purposes. We find out a perfect matching of our solution and the numerical one.
