Mechanisms of conversion of noise-like laser pulses into coherent pulses

Quantum and Nonlinear Optics VII, 2020
This report analyses possible mechanisms of conversion of noise-like laser pulses into coherent ones with comparatively high efficiency. It is demonstrated that incoherent or partly coherent pulses can be promising for phase-insensitive pumping in processes where the structure of pumping pulses is not related to the structure of generated/transformed ...

On the formation of noise-like pulses in fiber ring cavity configurations

Optical Fiber Technology, 2014
Abstract We give an overview of the current status of fiber-based noise-like pulse (NLP) research conducted over the past decade, together with presenting the newly conducted, systematic study on their temporal, spectral, and coherence characteristics in nonlinear polarization rotation (NPR)-based erbium-doped fiber ring cavity configurations ...

Noise-like pulses: useful or harmful?

Quantum and Nonlinear Optics VIII, 2021
Properties of noise-like pulses are analysed from the viewpoint of their employment as radiation carriers with relatively high energy. The difference from the well-known method of chirped pulse amplification consists in that instead of temporal stretching of a pulse prior to amplification, this technology relies upon redistribution of the pulse energy ...

Noise-like pulses in dispersion-controlled fiber lasers

Laser Physics Letters, 2023
Abstract Noise-like pulse generation in ring lasers in which the anomalous dispersion of the cavity fiber is partially compensated by using a normal-dispersion fiber has been studied by numerical simulation. Solitons moving in this cavity are periodically subjected to temporal compression in the anomalous-dispersion fiber and expansion ...

Control of sub-pulse duration in noise-like structures

Quantum and Nonlinear Optics VII, 2020
For the first time demonstrated are possibilities of control over the duration of sub-pulses within nanosecond noise-like pulse bunches, from 1.4 ps to 170 fs, through spectral filtering of radiation. The proposed method is implemented on the basis of an actively mode-locked Yb fibre laser.
