A mode-locked Nd:YAG laser is described which produces pulses 30 psec in duration at a 2.6 nsec repetition rate. The locking range extends over ≈35 GHz, although the free-running oscillating linewidth is only about 10 GHz. Also discussed is the behavior of the phase of the pulsetrain with changing cavity length.

Mode locking in solitary lasers
Optics Letters, 1991We present an analysis of passively mode-locked lasers in which pulse formation is dominated by the interplay between self-phase modulation and negative dispersion in separate cavity elements. Steady-state pulse parameters and stability issues are discussed.

Physical Review E, 2005
A characteristic property of nonlinear oscillatory systems is their ability to mode lock to a periodic, external, driving signal. In an n:m mode-locked state, the driven system executes n oscillations to every m oscillations of the driving signal, with a constant phase relationship between the two oscillations.

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
During the last decade, self mode-locking and resulting comb formation have emerged from a controversially discussed anomaly to a hot topic in semiconductor laser physics. Initial experimental reports claimed mode-locking in a cavity lacking the stabilizing action of a saturable absorber [1] .

Critical behavior of a passively mode-locked laser: rational harmonic mode locking
Optics Letters, 2007The 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.

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.

Optically injected mode-locked laser
Physical Review E, 2011We 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, 2011Monolithic 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., 2005It 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, 2013This 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.
