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.

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.

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.

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.

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.

A review of various types of active and passive mode-locked lasers is presented. Theoretical and experimental aspects of mode locking are covered. Stabilization schemes used in mode-locked laser systems are described. Techniques used in the measurement of the time duration of the ultrashort pulses and the uses of high-power, low-power, and picosecond ...

This chapter is devoted to the theoretical basics underlying the mode-locking of an oscillator. Section 2.1 intuitively describes the concept of locking the oscillator modes and the different regimes of ultrashort pulse formation. Section 2.2 shows the role of different effects on pulse and generation.
