Abstract

We fabricated a 20% modulation depth semiconductor saturable absorber mirror on a metal/dielectric mirror base, for ease of the growth restrictions. Using such a saturable absorber mirror, we obtained self-starting mode-locking in a ring erbium-doped fiber laser. The output pulse width was 170 fs and the repetition rate was 25.6 MHz.
