We report the first (to our knowledge) experimental observation of passive synchronization between a 1.03 mu m self-similar pulse and a 1.56 mu m bound-soliton bunch in a two-color mode-locked fiber laser. The self-similar pulse can form an effective potential well of several picoseconds to trap the copropagating bound solitons in the shared-fiber section. Such synchronization mechanism is supported by the experimental evidence of smaller time separation between the bound solitons under synchronization, In addition, the self-similar pulse and bound solitons can still remain locked under the periodic collision of another 1.56 mu m unlocked pulse train.

Passive synchronization is demonstrated between the self-similar Yb-fiber and the stretched-pulse Er-fiber mode-locked lasers. The pulse repetition rates of the two mode-locked lasers can keep locked when multiple-pulse bound states or periodic pulse collisions occur. (C)2009 Optical Society of America

Passive synchronization and polarization additive pulse mode-locking techniques are combined to generate simultaneously the 1.03 mu m and 1.53 mu m ultrashort pulses at the same pulse repetition rates from synchronized Yb-fiber and Er-fiber mode-locked lasers. (C)2008 Optical Society of America
