Synchronous mode-locking in multichannel fiber laser systems

Based on the numerical experiment techniques, we report the synchronous pulse generation in multichannel fiber laser systems. The laser arrays under study are conformed by two up to seven nonlinearly coupled doped fibers, separately pumped. Due to the nonlinear interaction between evanescent waves of the active modulated radiation in one of the fibers and the radiation in all other ones, the system achieves the time synchronization - in all channels - of the pulse generation. The characterization of these systems as well as the effect of symmetry breaking on the pulse characteristics are carried out. (C) 2001 Published by Elsevier Science B.V.
