Abstract
We demonstrate an ultrashort pulsed Yb-doped polarization-maintaining fiber laser which uses Gires–Tournois interferometers (GTI) for managing dispersion. The GTI placed in the oscillator cavity aims to compress the pulse. Resulting in a pulse with a duration of 78 fs. The fact that the laser does not require additional de-chirp makes it more compact and avoids the insertion loss of additional components. Experiments with different dispersion confirm the excellent dispersion-managed performance of GTI. As far as we know, the duration of 78 fs is the shortest pulse obtained by using intracavity GTI dispersion management in fiber lasers.
