The quantum properties of a collection of dipole-interacting three-level V- and -type atoms are investigated in the presence of external coherent sources and a thermal bath. It is demonstrated that both the steady-state collective populations and the spectral features of these samples can be manipulated by varying the temperature or especially the atomic-level spacings by, e.g., static magnetic fields.
