Research Progress on All-Polarization-Maintaining Mode-Locked Fiber Lasers

open access: yesPhotonics
This article reviews the research progress of all-polarization-maintaining mode-locked fiber lasers. Owing to their excellent resistance to environmental interference and high stability, all-polarization-maintaining mode-locked fiber lasers hold ...

Vector Dissipative Solitons in Graphene Mode Locked Fiber Lasers

open access: yes, 2010
Vector soliton operation of erbium-doped fiber lasers mode locked with atomic layer graphene was experimentally investigated. Either the polarization rotation or polarization locked vector dissipative solitons were experimentally obtained in a dispersion-

Multi-wavelength, all-solid-state, continuous wave mode locked picosecond Raman laser [PDF]

open access: yes, 2010
We demonstrate the operation of a cascaded continuous wave (CW) mode-locked Raman oscillator. The output pulses were compressed from 28 ps at 532 nm down to 6.5 ps at 559 nm (first Stokes) and 5.5 ps at 589 nm (second Stokes).

Nonlinear multimodal interference and saturable absorption using a short graded-index multimode optical fiber

open access: yes, 2013
A detailed investigation of the nonlinear multimodal interference in a short graded-index multimode optical fiber is presented. The analysis is performed for a specific device geometry, where the light is coupled in and out of the multimode fiber via ...

Multi-stabilities and symmetry-broken one-colour and two-colour states in closely coupled single-mode lasers [PDF]

open access: yes, 2014
We theoretically investigate the dynamics of two mutually coupled identical single-mode semi-conductor lasers. For small separation and large coupling between the lasers, symmetry-broken one-colour states are shown to be stable.

Numerical simulation for generation of stable single mode-locked pulses from QML laser with EO modulator and V3+:YAG

open access: yesResults in Physics, 2018
The instability of mode-locked pulses underneath Q-switched envelop limits the applications of Q-switched and mode-locked (QML) lasers. In this paper we present a developed theoretical model for QML laser at 1.3 µm.

Compact graphene mode-locked wavelength-tunable erbium-doped fiber lasers: from all anomalous dispersion towards all normal dispersion

open access: yes, 2010
Soliton operation and soliton wavelength tuning of erbium-doped fiber lasers mode locked with atomic layer graphene was experimentally investigated under various cavity dispersion conditions.

Noise characterization of a pulse train generated by actively mode-locked lasers [PDF]

open access: yes, 1996
We analyze the entire power spectrum of pulse trains generated by a continuously operating actively mode-locked laser in the presence of noise. We consider the effect of amplitude, pulse-shape, and timing-jitter fluctuations that are characterized by ...

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Passively Mode-Locked Erbium-Doped Fiber Laser and Application in Laser Thrombolysis

open access: yesPhotonics
Fiber lasers have been widely used in surgery with the development of fiber photonics. Since the human body is prone to myocardial infarction caused by blood clots, laser thrombolysis was proposed as a safe and efficient treatment.
