Efficient fiber Bragg grating and fiber Fabry-Pe'rot sensor multiplexing scheme using a broadband pulsed mode-locked laser [PDF]

open access: yes, 2005
A pulsed broadband mode-locked laser (MLL) combined with interferometric interrogation is shown to yield an efficient means of multiplexing a large number of fiber Bragg grating (FBG) or fiber Fabry-Perot (FFP) strain sensors with high performance ...

Graphdiyne for Ultrashort Pulse Generation in an Erbium-Doped Hybrid Mode-Locked Fiber Laser

open access: yesFrontiers in Physics, 2019
An erbium-doped hybrid passively mode-locked fiber laser based on few-layer graphdiyne (GDY) saturable absorber (SA) has been investigated for the first time. Hybrid mode-locked fiber laser is composed of non-linear polarization rotation (NPR) technology

Highly stable MXene (V2CTx)-based harmonic pulse generation

open access: yesNanophotonics, 2020
MXene as a novel two-dimensional (2D) material exhibits a lot of advantages in nonlinear optics. However, the common MXene, Ti3C2Tx and Ti2CTx nanosheets, easily suffer from degradation under ambient conditions, greatly limiting their practical ...

Generation of 48 fs, 1 GHz Fundamentally Mode-Locked Pulses Directly from an Yb-doped “Solid-State Fiber Laser”

open access: yesPhotonics, 2023
We demonstrate a fundamentally mode-locked Yb-doped “solid-state fiber laser” with a repetition rate of 1 GHz and a pulse duration of 48 fs. The nonlinear-polarization-evolution (NPE) mode-locking of the “solid-state fiber laser” enables up to 286 mW of ...

Triple-wavelength fiber ring laser based on a hybrid gain medium actively mode-locked at 10 GHz [PDF]

open access: yes, 2008
A fiber ring laser based on a hybrid gain medium that produces three simultaneously mode-locked wavelength channels is presented. The lithium niobate based modulator used to actively mode-lock the laser cavity at 10 GHz is birefringence compensated to ...

Short pulse generation with 40 GHz passively-mode locked Q-dashed Fabry-Pérot laser [PDF]

open access: yes, 2009
Generation of sub-picosecond pulses by a DC-biased passively mode-locked Fabry-Perot laser is demonstrated. By using a tunable band-pass filter, it is observed that the width of the generated pulses decreases in direct proportion to the optical modes ...

Linearly Polarized 1180-nm Raman Fiber Laser Mode Locked by Graphene

open access: yesIEEE Photonics Journal, 2012
In this paper, we demonstrate a linearly polarized 1180-nm passively mode-locked Raman fiber laser using graphene-based saturable absorber (SA). The pump source is a linearly polarized ytterbium-doped fiber laser at 1120 nm. Stable nanosecond mode-locked

A hybrid mode locked laser as millimetre wave modulated data source for radio-over-fiber systems [PDF]

open access: yes, 2009
The paper presents a characterisation of a hybrid mode locked laser under external injection locking. It shows how such a system can be used to transmit baseband data without the requirement of an external ...

860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)

open access: yesResults in Physics, 2019
We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated
