14.5 GHz passive harmonic mode-locking in a dispersion compensated Tm-doped fiber laser

Abstract We demonstrate a high repetition rate passive harmonic mode-locking (HML) based on nonlinear polarization evolution (NPE) technique in a Tm-doped ring fiber laser cavity. Small net anomalous cavity dispersion based on dispersion compensation benefited the generation of high repetition rate...
