M. Han et al., 10GHz,2ps, pedestal-free ultra-short pulse generation using DSF and dispersion-imbalanced nonlinear loop mirrors, ACT PHY C E, 49(4), 2000, pp. 751-755
It is well known that the pulse compressed in Dispersion - shifted Fibers (
DSF) has pedestals. In this paper we de sign a new structure which combined
DSF and Dispersion - Imbalanced Nonlinear Loop Mirror (DI - NOLM) for puls
e compression and pedestal suppression. Using this structure, the lips puls
e with the repetition rate 10GHz generated from an active mode-locked fiber
ring laser (AM-MLFRL) was compressed to 2ps without pedestal.
