NOISE IN PULSED INJECTION LOCKING OF A PASSIVELY MODELOCKED LASER

In this paper, noise effects related to pulsed injection locking of a passively modelocked laser (PML) are analyzed. A set of nonlinear equa tions, derived from a soliton perturbation method, is used to describe the modelocked laser pulse evolution, under injection locking, The eq uations are linearized, and the stability of the injection locked solu tion is studied, Subsequently, the linear equations are employed to de scribe the coupling of both the injected signal noise and the internal noise, to the locked pulses, Noise reduction due to the injection pro cess is demonstrated, with important implications for all optical sign al regeneration and synchronization.
