Abstract
The influence of pump-field phase diffusion on the gain in a non-degen erate double-LAMBDA non-inversion laser is studied. The phase diffusio n of the lower-level coherence leads to loss contributions which are n ot directly proportional to the number density of atoms and occur in a ddition to the well known effect of reduced coherent population trappi ng. Lasing without inversion is however still possible even if the pha ses of the pump fields are not locked.
