Laser dynamics of asynchronous mode-locked fiber lasers
2013 6th IEEE/International Conference on Advanced Infocomm Technology (ICAIT), 2013New laser dynamics of asynchronous mode-locked fiber lasers will be reviewed in details, with the emphases on the interesting repetition frequency pulling effect and the all-normal dispersion operation state of asynchronous mode-locking.

Actively Mode-Locked Fiber Lasers
SPIE Proceedings, 1990We review recent investigation into the active mode-locking of rare earth doped silica, monomode fiber lasers. Dopants include Nd3+, Er3+ and Yb3+:Er3+ and mode-locking has been accomplished either by amplitude modulation or by phase modulation. Both bulk optic and integrated optic modulators have been used. Pulses of 4 psec duration have been observed

Mode-locked Holmium fiber lasers
Nonlinear Optics, 2017We develop a computational model of a holmium-based laser which produces robust mode-locking at 2.9 microns with peak powers in the tens of kilowatts, far exceeding current fiber laser performance at 1.5 microns.

Mode-locked fiber lasers based on Tm-doped and Tm-Ho-codoped silicate fibers have been studied. The first modelocked fiber laser oscillator beyond 2 μm was demonstrated. The first mode-locked 2μm fiber laser with ~GHz repetition rate was demonstrated. The broadest spectrum (50nm FWHM) was obtained from dispersion managed 2μm mode-locked fiber laser.

Soliton mode-locked fiber laser for distance measurements
Applied Optics, 2021Absolute distance measurement is crucial for many applications including metrology, large-scale manufacturing, range finding, and surveying. In this paper, a novel, to the best of our knowledge, technique is introduced for precise distance measurement by including the distance under measurement in a soliton mode-locked fiber ring laser (SMFRL ...

Mode-locked fiber lasers based on doped fiber arrays
Applied Optics, 2014We designed a new kind of mode-locked fiber laser based on fiber arrays, where the central core is doped. A theoretical model is given for an all-fiber self-starting mode-locked laser based on this kind of doped fiber array. Two different kinds of fiber lasers with negative dispersion and positive dispersion are simulated and discussed. The stable mode-

Automatic mode-locking fiber lasers: progress and perspectives
Science China Information Sciences, 2020Polarization control in nonlinear polarization rotation based mode-locked fiber lasers is a long-term challenge. Suffering from the polarization drifts induced by environmental disturbances, nonlinear polarization rotation based mode-locked fiber lasers is difficult in continuously operating under the desired pulsation regime thereby substantially ...

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.
