Mode-locking dissected [PDF]

open access: yesNature Physics, 2020
Despite the wide use of mode-locked lasers, no general theory for mode-locking exists. An attractor dissection approach provides some intuitive understanding of the complex dynamics in one type of mode-locking.

Mode locking mechanism in Fourier-domain mode-locked optoelectronic oscillators

open access: yesOptics Express
Fourier-domain mode-locked (FDML) optoelectronic oscillators (OEOs) are regarded as a promising candidate to generate linearly chirped microwave waveforms (LCMWs) with large time-bandwidth products. Nevertheless, up to date, the mode locking mechanism in FDML-OEOs is still not clear enough.

Active mode-locking via pump modulation in a Tm-doped fiber laser

open access: yesAPL Photonics, 2016
We propose and experimentally realize a new class of actively mode-locking technique using pump modulation for rare-earth doped fiber lasers. A Tm-doped fiber laser at 2 μm is mode-locked using the proposed active mode-locking via pump modulation ...

Active mode-locking optoelectronic oscillator

open access: yesOptics Express, 2020
The optoelectronic oscillator (OEO) has been widely investigated to generate ultra-pure single-frequency microwave signals. In this study, we propose and experimentally demonstrate an active mode-locking optoelectronic oscillator (AML-OEO), which can generate broadband microwave frequency comb (MFC) signals.

Dynamics Simulation of Self-Mode-Locking in a Semiconductor Disk Laser Using Delay Differential Equations

open access: yesPhotonics, 2022
Self-mode-locked semiconductor disk lasers possess compact resonant cavity and stable construction. These devices have a wide application prospect because of their picosecond to sub-picosecond pulse width, excellent beam quality and tailorable emission ...

Relocking and Locking Range Extension of Partially Locked AMLL Cavity Modes with Two Detuned RF Sinusoids

open access: yesPhotonics, 2023
Actively mode-locked fiber ring lasers (AMLLs) with loss modulators are used to generate approximately 100ps pulses with 100MHz repetition. RF detuning around the fundamental frequency, f0, causes a loss in phase lock (unlocking) of cavity modes and ...
