Paper Abstract

We demonstrate an all fiber mode-locked ultrafast erbium laser oscillator by means of nonlinear polarization evolution (NPE) in polarization maintaining (PM) fibers. Here, the artificial saturable absorber (SA) is formed by a piece of PM active fiber and a Faraday mirror (FM). High repetition rate could be obtained thanks to the introduction of the PM active fiber. The transmission characteristics of the SA are studied through theoretical analyses as well as experimental demonstration. Channeled spectra caused by soliton-soliton interaction and birefringence-induced filter are also studied and discussed. A good agreement is achieved between the theoretical analyses and experimental results.
