ABSTRACT:
The output power of a passively modelocked fiber laser is increased by distributing optical losses throughout the cavity. The laser cavity includes a saturable absorber and a polarizing element that serves as the output coupler, and these are positioned on opposite sides of the fiber gain medium. The pump light is preferably injected towards the side of the laser cavity that includes the saturable absorber. The laser cavity compensates for polarization drifts and is environmentally stable.
