摘要

We demonstrate, for the first time to our knowledge, a self-starting passive harmonic mode-locked femtosecond Yb~(3+)-doped fiber laser with a scalable repetition rate of up to 585 MHz and >45 dB of supermode suppression. Pulse-to-pulse jitter of ~14 ps is measured by optical cross correlation at the ninth harmonic, and radio-frequency (RF) spectrum measurements show that certain correlations exist between pulses in harmonic mode. Our results suggest that one of the proposed passive harmonic mode-locking mechanisms may be dominant for this laser.
