We prove that population trapping depends on the relative polarizations between the pump and generated fields in a double-ssV laser system. Orthogonal linear field polarizations can lead to total suppression of emission. An interpretation of this alternative mechanism of inversion without amplification is given in the context of a dressed-atom formalism. © 1994 The American Physical Society.
