Low repetition-rate all-normal-dispersion mode locking laser based on SESAM

In this paper, we describe a compact all-fiber-path picosecond pulse based on Ytterbium doped fiber oscillator.

Description
Summary:In this paper, we describe a compact all-fiber-path picosecond pulse based on Ytterbium doped fiber oscillator. A home-made novel SESAM mounted on fiber is reported, by which stable mode locking is obtained. We observe the appearance of multiple pulsing, and give an explanation with regard to establishment of multiple pulsing. The fiber laser generates 15 ps pulse trains without a dispersive delay line or anomalous dispersion in the cavity. Mode locking pulse with 17 MHz low repetition-rate was produced, with 10 mW average output power at 1064 nm.
