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

We report experimental as well as theoretical investigation of the key factors that influence the relative timing jitter between hybrid synchronized ultrafast Yb and Er fiber laser systems. Experimental results show that, within the achievable synchronization range, the synchronization performance varies significantly with the relative injection timing between the 1 mu m master and 1.5 mu m slave pulses. This observation is in agreement with the insights obtained from the theoretical analysis, which identifies the retiming effect as a function of the initial condition of the master-slave pulse collision. By controlling the relative injection timing with a low-bandwidth intracavity feedback, relative timing jitter as low as 0.87 fs (within 1.9 MHz bandwidth) is successfully obtained.

The relative timing between the injection and slave pulses is found to be the key factor to achieve sub-fs timing jitter (0.87 fs, 1.9 MHz bandwidth) between Yb-fiber and Er-fiber fs lasers with hybrid synchronization.
