Frequency shifted feedback and frequency comb generation in an Er3+-doped laser

Perry, I.R., Wang, R.L. and Barr, J.R.M. (1994) Frequency shifted feedback and frequency comb generation in an Er3+-doped laser Optics Communications, 109, (1-2), pp. 187-194. (doi:10.1016/0030-4018(94)90758-7).

Record type: Article


The temporal and spectral characteristics are reported of an Er3+ -doped fibre laser incorporating frequency shifted feedback. The output of the free running laser was found to be either continuous-wave or train of driven relaxation oscillations depending on cavity loss. The performance is described and a simple theoretical model is used to predict the main features. Under cavity matching conditions, a train of pulses was generated with a repetition rate equal to the roundtrip time. Injection seeding of the laser generated a discrete comb of optical frequencies for applications in optical metrology.
