Abstract

Robust synchronization was achieved for Ti:sapphire, Yb- and Er-doped fiber mode-locked lasers in a master–slave configuration. Square nanosecond pulses were generated in the long-cavity fiber lasers, while synchronization was maintained owing to resonance-enhanced cross-absorption modulation in an additional Er-doped fiber, allowing for a cavity mismatch tolerance of 8.2 and 3.6cm, respectively. This is the highest tolerable cavity-length difference ever obtained for synchronized mode-locked lasers.

Repetition rates of the (a) Yb- and (b) Er-fiber lasers under different cavity length mismatches. The synchronized repetition rate is at 239.403 kHz . The diagonal lines illustrate the cavity-length-dependent repetition rates of the nonsynchronized fiber lasers, while the “stair-step” lines show the fixed repetition rates of the slave lasers operated at synchronization mode.

Fig. 3
Fig. 3

Output pulses of (a) Yb- and (b) Er-fiber lasers measured by changing the average injection power. The pulses were recorded by a digital oscilloscope (TDS 6604, bandwidth of 6 GHz ). The Yb- and Er-fiber laser pulses were deformed from 10 to 2 ns and from 5 to 1 ns with the average injection power decreasing from 10.6 to 1.9 mW and from 8.2 to 4.3 mW , all respectively. The minimum injection master power to keep the Yb- and Er-fiber laser mode-locked was 1.9 and 4.3 mW , respectively.

(b) Jitter PSD of the Ti:sapphire and Er-fiber laser. (c) Jitter PSD of the two fiber lasers. All of the three timing jitters are integrated from 1 Hz to 50 kHz .
