Abstract

A promising method for pulse compression is the use of an additional cavity which contains the optical fiber—additive-pulse mode-locking (APML). The theoretical models of APML have been limited mostly by qualitative analysis of the pulse-compression mechanism. In Ref. 1 the interferometric combination of pulses on the coupling mirror was considered and the conditions for maximal compression were obtained. Experimental study of APML² shows that, in these nonlinear systems, the stability of the output pulse train is strongly determined by the parameters of modulation (for example, modulation frequency), and various dynamic regimes are demonstrated. However, the origins of such instabilities are still unknown.
