Abstract

Two mode-locked femtosecond fiber lasers, connected via a 7km fiber link, are synchronized to an rms timing jitter of 19fs, observed over the entire Nyquist bandwidth (half of the 93MHz repetition frequency). This result is achieved in two steps. First, active cancellation of the fiber-transmission noise reduces timing jitter caused by path length fluctuations to a record level of 16fs. Second, using a wide bandwidth interactivity actuator, the slave laser is synchronized to the incoming stable pulse train from the reference laser to within 10fs. These results are confirmed by an optical cross-correlation measurement performed independently of the feedback loop operated in the microwave domain.

Fig. 1

Schematic of the transfer and local synchronization setup. The synchronization loop compares the incoming pulse train, which is stabilized via a fiber noise cancellation loop, with the slave laser’s pulse train; the resulting error signal is fed back to the intracavity EOM and PZT of the slave laser. The cross correlation is performed locally.

Fig. 2
Fig. 2

In-loop error signal for (a) local synchronization, (b) fiber noise cancellation, and out-of-loop error signal for (c) long-distance synchronization. All plots are shown over a 1 Hz to 100 kHz integration bandwidth. The fiber noise cancellation loop has 16 fs of timing jitter, the local synchronization has 10 fs of timing jitter, and the long-distance synchronization has a timing jitter of 19 fs .

Optical cross-correlation measurement of the timing jitter for (a) local synchronization, and (b) long-distance synchronization. Both traces show the rms timing jitter within the Nyquist bandwidth ( 50 MHz ) .
