Abstract

Ultrafast-ultralong ring fiber lasers represent a new passively mode-locked laser architecture reliant on the use of Raman-assisted nonlinearity management over cavities extending tens of kilometers and fast, polarization-insensitive saturable absorption. These new sources are capable of supporting the generation of stable pulses shorter than 200 fs with ultra-low repetition rates of a few tens of kHz, overcoming previous limitations to pulse duration and peak power imposed by dispersive effects. The unique characteristics of this new family of ultrafast fiber oscillators makes them suitable for a broad range of applications. In this invited talk we will review some of the latest advances on the topic, focusing on the optimal design and implementation of such lasers.
