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] .

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.

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.

Optical Engineering, 1992
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 ...

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.

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.
