Maiboroda, A. N.; Malyshev, V. A. The analysis of free oscillations stability of triple level quantum systems with upper working transition. (Russian) Zbl 1224.78042 Izv. Vyssh. Uchebn. Zaved., Sev.-Kavk. Reg., Estestv. Nauki 2009, No. 5, 49-52 (2009). The method of the laser dynamics developed by the second author in his monograph is applied here to analyze stability regimes for a general three-level quantum system. The analytically found inequalities are analyzed by numerical methods.
