## Abstract A modified injection seeding setup, which can generate low jitter single mode picosecond optical pulses independent of the repetition rate in principle, was presented in this article. With a gain‐switched DFB laser diode employed as the external injection seeding, a gain‐switched Fabry–

✦ Synopsis
Robust synchronization was achieved in a hybrid configuration for three-color high-repetition-rate ultrashort modelocked lasers around 800, 1030, and 1560 nm due to fractional amplification and enhanced cross-phase modulation. This hybrid synchronization scheme permits the achievements of timing jitter of 550 as between 800-nm and 1030-nm pulses by fractional amplification, and 8.3 fs between the 1030-nm and 1560-nm pulses by cross-phase modulation. The low timing jitter between 800nm and 1030-nm pulses was commensurate with the broad emission band of the Ti:Sapphire laser.
