Modeling of the radiation conversion between the IR and visible ranges on competitive optical transitions in manganese vapors

The work is devoted to the results of the modeling the manganese vapor active medium that takes into consideration the competition between the optical transitions in the IR and visible ranges. We model the radiation conversion between the visible and IR ranges due to such competition. The qualitative and quantitative features of such conversion on various pulse repetition rates are discussed. In particular, we show that the conversion from the IR range to the visible range is more effective than opposite one. Based on the modeling results, we suggest the way of further studies on the experimental realization and measuring of such conversion.
