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.
