Abstract
A probe field propagation in a medium of two-level Jg equals .5 yields Je equals .5 atoms, has been theoretically investigated. The atoms are pumped by a circular polarized optical field. An applied static magnetic field is orthogonal to the direction of the pump field propagation. The case of the pump is a coherent field and Gaussian- Markovian random process with a finite bandwidth of the noise have been analyzed. We have obtained that one of the normal waves can amplify in the absence of population inversion both for coherent and partially coherent pump. For the pump with a finite-bandwidth amplification occurs when the Larmor frequency and the Raby frequency of the pump are of the order of the pump linewidth, which was taken much broader than the natural width of the excited state.
