Abstract
The authors report the operation of a harmonically and regeneratively modelocked erbium fibre ring laser at for the first time. Harmonic regenerative modelocking was achieved by feeding back the harmonic longitudinal beat signal which was detected with a high speed photodetector and a high Q dielectric filter. The repetition rate was 10GHz and the soliton effect shortened'the pulse width from 7,0 to 2.7 ps.
