In this work, we report a >100 W femtosecond (fs) burst mode all-fiber laser system at 1.0 µm that operates at an intra-burst repetition rate of up to 1.2 GHz. This fiber laser system provides the highest output power that has been reported so far for GHz fs fiber lasers, to the best of our knowledge. In addition to the superior output power, this fiber laser system also shows a promising overall figure of merit, specifically in terms of pulse width (473 fs), long-term reliability (<0.67% power fluctuation) and system compactness (all-fiber configuration). We anticipate that this all-fiber laser system can be a promising ultrafast laser source for these applications requiring fs pulses with both high average power and high repetition rate, such as micromachining, bioimaging and frequency metrology.
