MXene saturable absorber enabled hybrid mode-locking technology: a new routine of advancing femtosecond fiber lasers performance

open access: yesNanophotonics, 2020
MXene is a promising two-dimensional (2D) material that is widely used in electro-photonic devices due to its unique properties. In this contribution, V2CTx, a novel MXene, was employed as a saturable absorber (SA) for hybrid passively mode-locked fiber ...

Narrow-linewidth short-pulse III-V-on-silicon mode-locked lasers based on a linear and ring cavity geometry.

open access: yesOptics Express, 2015
Picosecond-pulse III-V-on-silicon mode-locked lasers based on linear and ring extended cavity geometries are presented. In passive mode-locked operation a 12 kHz -3dB linewidth of the fundamental RF tone at 4.7 GHz is obtained for the linear cavity ...

Characterization of timing jitter spectra in free-running mode-locked lasers with 340  dB dynamic range over 10 decades of Fourier frequency. [PDF]

open access: yesOptics Letters, 2014
We demonstrate a method that enables accurate timing jitter spectral-density characterization of free-running mode-locked laser oscillators over more than 10 decades of Fourier frequency from mHz to tens of MHz range.

Algorithm based comparison between the integral method and harmonic analysis of the timing jitter of diode-based and solid-state pulsed laser sources [PDF]

open access: yes, 2015
A comparison between two methods of timing jitter calculation is presented. The integral method utilizes spectral area of the single side-band (SSB) phase noise spectrum to calculate root mean square (rms) timing jitter. In contrast the harmonic analysis

Breathing dissipative solitons in mode-locked fiber lasers

open access: yesScience Advances, 2019
Oscillating dissipative solitons and their bound states are captured in ultrafast lasers using real-time measurement techniques. Dissipative solitons are self-localized coherent structures arising from the balance between energy supply and dissipation ...

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.

Tunable and switchable dual wavelength lasers using optical fibre Bragg grating external cavities [PDF]

open access: yes, 2002
Two novel external cavity lasers are demonstrated experimentally. The first utilises a Bragg grating fabricated in highly birefringent optical fibre and offers the ability to switch between modes that are separated in polarisation and wavelength.

Volume Bragg grating external cavities for the passive phase locking of high-brightness diode laser arrays : theoretical and experimental study [PDF]

open access: yes, 2011
We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as
