On the stability of lateral self-mode locking in an injection laser

The problem of coexistence and lateral self-mode locking in the resonator of an injection laser with a parabolically inhomogeneous permittivity is considered. The stability of the self-mode-locking process and factors causing its disturbance are studied. It is shown that the appearance of nonequidistant lateral modes due to the dependence of the refractive-index profile in a medium on the concentration of nonequilibrium carriers is the main cause of disturbing the self-mode-locking regime.
