Generation and characterization of erbium-Raman noise-like pulses from a figure-eight fibre laser
, 2021 We report an experimental study of the noise-like pulses generated by a ~300 m long passively mode-locked erbium-doped figure-eight fibre laser. Non-self-starting mode locking yields the formation of ns scale bunches of sub-ps pulses.

EURASIP Journal on Advances in Signal Processing, 2009 Harmonics-to-noise ratios (HNRs) are affected by general aperiodicity in voiced speech signals. To specifically reflect a signal-to-additive-noise ratio, the measurement should be insensitive to other periodicity perturbations, like jitter, shimmer, and ...

Impact of spectral filtering in coexistence of noise-like pulse and dissipative soliton
APL PhotonicsWith the introduction of the Lyot–Sagnac filter, the laser enables the coexistence of noise-like pulse (NLP) and dissipative soliton (DS) outputs with switchable wavelength intervals, which is observed for the first time. A simulation model of a ytterbium-doped mode-locked fiber laser is also constructed, and the filtering effect is found to play an ...
