Mode-locking dissected [PDF]

Nature 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.

Experimental Investigation of the Wavelength Tunability in All-Normal-Dispersion Ytterbium-Doped Mode-Locked Fiber Lasers

IEEE Photonics Journal, 2013
The wavelength tunability of all-normal-dispersion (ANDi) ytterbium (Yb)-doped mode-locked fiber laser is experimentally investigated, where the laser is mode-locked by nonlinear polarization rotation and the wavelength is adjusted by an intracavity ...

Mode-Locking Thulium-Doped Fiber Laser With 1.78-GHz Repetition Rate Based on Combination of Nonlinear Polarization Rotation and Semiconductor Saturable Absorber Mirror

IEEE Photonics Journal, 2017
We experimentally demonstrate a passively mode-locking thulium-doped fiber laser based on the combination of the nonlinear polarization rotation (NPR) and the semiconductor saturable absorber mirror (SESAM).

Optically injected mode-locked laser

Physical Review E, 2011
We study analytically and numerically a delay differential model of a passively mode-locked semiconductor laser subjected to a single frequency coherent injection. The width of the locking cone is calculated asymptotically in the limit of small injection and compared to that obtained by direct numerical integration of the model equations.

Spatio-Temporal Mode-locking in Quadratic Nonlinear Media

, 2020
A new theoretical model is developed to characterize spatio-temporal mode-locking (ML) in quadratic nonlinear media. The model is based on the two-dimensional nonlinear Schr\"odinger equation with coupling to a mean term (NLSM) and constructed as an ...

1.55 µm AlGaInAs/InP sampled grating laser diodes for mode-locking at THz frequencies [PDF]

, 2018
We report mode locking in lasers integrated with semiconductor optical amplifiers, using either conventional or phase shifted sampled grating distributed Bragg reflectors(DBRs).

Switchable Dual-Comb Fiber Laser Based on Sagnac Loop for Wavelength-Multiplexing and Polarization-Multiplexing

Photonics
We present an all-fiber erbium-doped mode-locked laser capable of switching among continuously tunable single-pulse mode-locking, wavelength-multiplexing asynchronous-pulse mode-locking, and polarization-multiplexing asynchronous-pulse mode-locking ...

Mode-locking in driven vortex lattices with transverse ac-drive and random pinning

, 2001
We find mode-locking steps in simulated current-voltage characteristics of driven vortex lattices with {\it random} pinning when an applied ac-current is {\it perpendicular} to the dc-current.

Dynamic melting of confined vortex matter [PDF]

, 2003
We study {\em dynamic} melting of confined vortex matter moving in disordered, mesoscopic channels by mode-locking experiments. The dynamic melting transition, characterized by a collapse of the mode-locking effect, strongly depends on the frequency, i.e.

Phase diagram and complexity of mode-locked lasers: from order to disorder

, 2008
We investigate mode-locking processes in lasers displaying a variable degree of structural randomness, from standard optical cavities to multiple-scattering media.
