 note = {An amplification of the Gaussian beams in an active gaseous medium, possesing a quadratic radial variation of the population inversion, is considered. The gain curve is shown to have an asymmetrical shape. For a given population inversion, the maximum gain is calculated to be attainable at higher frequency than that of the atomic resonance, both in unsaturated and saturated operations.},
