M. Nakazawa et E. Yoshida, A 40-GHz 850-fs regeneratively FM mode-locked polarization-maintaining erbium fiber ring laser, IEEE PHOTON, 12(12), 2000, pp. 1613-1615
An 850-fs pulse train at 40 GHz was directly generated From a regenerativel
y FM mode-locked fiber laser. The soliton effect was used to generate a sho
rt pulse and to suppress the supermode noise. The laser was locked to an ex
ternal signal by a phase-locked loop (PLL) technique and the wavelength was
tunable between 1540 and 1555 nm.
