Widely Tunable Actively Modelocked Erbium Fibre Ring Laser

Abstract

Erbium fibre lasers offer a large variety of features such as large tuning range /1/, high output power /1/, modelocking at repetition rates beyond 10 GHz /2/, Q-switching /3/ and single longitudinal mode opera tion /4/. In this paper we present a 980 nm laser diode pumped erbium-doped fibre ring laser that combines a large tuning range of 33 nm with picosecond pulse generation by active modelocking at repetition rates up to 6 GHz.
