Critical behavior of a passively mode-locked laser: rational harmonic mode locking

Optics Letters, 2007
The critical behavior of passive mode locking has been demonstrated in a figure-eight fiber laser that performs rational harmonic mode locking (RHML). On both the repetition rate and the pulse amplitude distribution, the observed pulse trains near the threshold exhibit the same regulations as the rational harmonic mode-locked ones.

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.

AlGaInAs mode-locked lasers for ultrashort pulse harmonic mode locking

2011 13th International Conference on Transparent Optical Networks, 2011
Monolithic AlInGaAs compound-cavity lasers for harmonic ML at multi-GHz frequencies have been fabricated and assessed. Optical pulses of ∶ 1 ps long at 160 GHz have been obtained. The optimal cavity and reflector design has been investigated experimentally and theoretically.

Mechanism of harmonic mode locking of the regeneratively mode-locked laser diode

2004 IEEE 19th International Semiconductor Laser Conference, 2004. Conference Digest., 2005
It was found that the harmonic frequency optical injection locking of the regeneratively mode-locked laser diode occurs through the difference frequency component generation. Synchronization with up to 320-GHz input was also confirmed.

An automatic mode-locked system for passively mode-locked fiber laser

SPIE Proceedings, 2013
This paper designs and implements one kind of automatic mode-locked system. It can adjust a passively mode-locked fiber laser to keep steady mode-locked states automatically. So the unsteadiness of traditional passively mode-locked fiber laser can be avoided.

Mode‐Locked Soliton Lasers

SIAM Review, 2006
A comprehensive treatment is given for the formation of mode-locked soliton pulses in optical fiber and solid state lasers. The pulse dynamics is dominated by the interaction of the cubic Kerr nonlinearity and chromatic dispersion with an intensity-dependent perturbation provided by the mode-locking element in the laser cavity.

Polarization-multiplexed, dual-comb all-fiber mode-locked laser

Photonics Research, 2018
Mode-locked fiber lasers that can simultaneously generate two asynchronous ultrashort pulse trains could play an attractive role as the alternative light sources for low-complexity dual-comb metrology applications.

Mode locking in tokamaks

Nuclear Fusion, 1990
The theory of non-linear tearing modes has been extended to include the effects of rotation and interaction with a resistive wall. The time dependent solution of the resulting equations shows a spatial locking of the mode similar to that observed in tokamak experiments.

Passive Mode Locking

1987
The technical requirements for active mode locking, as described in the previous two chapters, are not simply fulfilled. The external source for driving the modulator must be accurately frequency stabilized at the pulse repetition frequency. An alternative for obtaining short pulses, called passive mode locking, does not require these complications ...
