    "abstract": "The semi-classical solution of the three state system is considered to study\nthe population inversion at and away from resonance. At resonance, it is shown\nthat if the system is initially populated either in the upper or in the lower\nlevel, then the population oscillation occurs in a way which is quite different\nfrom that if it is initially populated in the middle state. At off resonance,\nthere is gradual suppression of the population in the excited states and in the\nasymptotic limit of the detuning, the system returns to its initial state.",
