Conference on Lasers and Electro-Optics, 2020
A new mode-locking mechanism is discussed that solely relies on four-wave mixing and does not require a saturable absorber. This mechanism explains a number of previously reported peculiar findings of self-modelocking and comb formation.

IEEE Journal of Selected Topics in Quantum Electronics, 2000
The evolution of the theory of mode-locking over the last three and a half decades is reviewed and some of the salient experiments are discussed in the context of the theory. The paper ends with two-cycle pulses of a mode-locked Ti:sapphire laser.

Mode locking in tokamaks [PDF]
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.

Revealing the Buildup Dynamics of Harmonic Mode‐Locking States in Ultrafast Lasers
Laser & Photonics reviews, 2019Harmonic mode‐locking (HML) is an important technique enabling the generation of high‐repetition‐rate ultrashort pulses. Using an emerging time‐stretch dispersive Fourier transform technique, the experimental observation of the entire buildup process of ...

Revealing the Transition Dynamics from Q Switching to Mode Locking in a Soliton Laser.
Physical Review Letters, 2019Q switching (QS) and mode locking (ML) are the two main techniques enabling generation of ultrashort pulses. Here, we report the first observation of pulse evolution and dynamics in the QS-ML transition stage, where the ML soliton formation evolves from ...

A theory of noise in mode-locked lasers is developed that applies to additive pulse mode-locked and Kerr lens mode-locked systems. Equations of motion are derived for pulse energy, carrier linewidth, frequency pulling, and timing jitter. The effect of gain fluctuations, mirror vibrations, and index fluctuations are determined.
