Abstract We develop a nonlinear theory of lasing without inversion in a four level atomic system. The appearance of lasing without inversion is the result of atomic coherence induced between two lower levels by a Raman process. We consider both nondegenerate and degenerate configurations and obtain expressions for the linear gain and the laser output intensity. We identify the conditions for ideal lasing without inversion.
