Tailored Design of Mode-Locking Dynamics for Low-Noise Frequency-Comb Generation

Implementation of femtosecond fiber lasers has revolutionized the field of optical frequency combs. Even though Yb-fiber combs have a much more convenient wavelength range, the field is dominated by Er-fiber combs, due to the difficulty of satisfying multiple constraints at 1 \ensuremath{\mu}m. This study overcomes the difficulty by a design of the mode-locking dynamics that succeeds in generating energetic pulses 33 fs long, without using higher-order dispersion compensation, and while ensuring that the laser operates at a net cavity dispersion of zero, for low-noise supercontinuum generation.
