MULTIMODE EFFECTS ON THE EVOLUTION AND LONG-TERM STABILITY OF A PASSIVELY MODE-LOCKED LASER UNDER PULSED INJECTION LOCKING

A multidimensional extension of the injection locking of CW lasers has been recently presented and experimentally verified when both a passi vely and an actively mode-locked laser were locked to injected coheren t pulse trains, Harmonic injection locking of a passively mode-locked laser, where a subset of the laser cavity modes were lacked to the inj ected signal, was also recently realized in a fiber laser to yield tra ins of 6-ps pulses at rates of up to 40 GHz, In this paper, the multim ode injection-locking process is addressed with an emphasis on the lon g-term dynamics of the laser, pulse buildup under injection locking, m emory effects, noise mechanism as well as potential applications, e.g. , optical signal regeneration, Using a recently introduced formalism f or describing passively mode-locked lasers, the experimental results a re compared to numerical simulations.
