The main idea of lasing without inversion is the cancellation of absorption which leads to amplification (and laser) even if population inversion is not present. Such a situation is realized in three level atomic configurations where two coherent atomic transitions interfere destructively. In the present work, we describe the salient features where the situation is analogous to the double slit experiment.
