H. Zandi A. Bahrampour Journal Article 2019 11 26   Several theoretical models for description of the injection locking lasers are presented by previous investigators. Nearly in all of these theories, the temporal and spatial variations of gain of the active medium is neglected. In these theories there levant difference equation of the boundary condition of the input mirror is approximated by an ordinary differential equation and solved. In this paper a classical model for the behavior of the active medium is presented and the governing equations are solved. The time variation of the output power for the injection frequencies are calculated. The results for several detuning angels are presented in this paper, the results are in good agreement with the previous published data.   Several theoretical models for description of the injection locking lasers are presented by previous investigators.
