Noise-like pulse trapping in a figure-eight fiber laser
Optics Express, 2015 We report on the trapping of noise-like pulse in a figure-eight fiber laser mode locked by nonlinear amplifier loop mirror (NALM). After achievement of noise-like vector pulse, it was found that the wavelength shift of the two resolved polarization components responsible for the pulse trapping was very sensitive to the cavity birefringence. By properly

Generation of widely tunable picosecond pulses with large SMSR by externally injecting a gain-switched dual laser source [PDF]
, 2004 The authors demonstrate a procedure of generating picosecond optical pulses that are tunable over a wide wavelength range (65 nm) and have very high spectral purity side-mode suppression ratio [(SMSR)>60 dB].

Corn plants as temporary acoustic barrier to limit the effects of noise pollution
, 2021 Corn is a cereal imported into Europe from the Americas. It is used for human and animal feed, but there are also industrial uses such as the production of ethanol, of fuel for heating homes, or the production of starch. Corn grows in the summer in areas

Noise-like pulse in a gain-guided soliton fiber laser
Optics Express, 2007 We report on the operation of a passively mode-locked fiber ring laser made of purely positive dispersion fibers and mode-locked by using the nonlinear polarization rotation technique. It was experimentally found that apart from the gain-guided soliton operation the laser can also emit a kind of noise-like pulse. We show numerically that the noise-like

Integer and fractional charge Lorentzian voltage pulses analyzed in the frame of Photon-assisted Shot Noise [PDF]
, 2013 International audienceThe periodic injection $n$ of electrons in a quantum conductor using periodic voltage pulses applied on a contact is studied in the energy and time-domain using shot noise computation in order to make comparison with experiments. We

Simulation for Generation of Several Types of Pulses in an Yb-Doped Mode-Locked Fiber Laser
IEEE Photonics Journal, 2020 We numerically demonstrated six types of pulses in an Yb-doped fiber laser, including dissipative soliton (DS), dissipative soliton resonance (DSR), multipulse, noise-like pulse (NLP), breathing soliton and soliton explosion.

An improved method for signal de‐noising based on multi‐level local mean decomposition
Engineering Reports, 2023 The product functions (PFs) extracted by local mean decomposition (LMD) of the noisy signal contain obvious energy‐concentrated pulses. As a result, the conventional amplitude threshold filtering used in wavelet transform (WT)‐based and empirical mode ...
