The influence of pump-field phase diffusion on the gain in a non-degenerate double- non-inversion laser is studied. The phase diffusion of the lower-level coherence leads to loss contributions which are not directly proportional to the number density of atoms and occur in addition to the well known effect of reduced coherent population trapping. Lasing without inversion is however still possible even if the phases of the pump fields are not locked. 1994.
