Mode-locked ytterbium fiber lasers
Applied Optics, 2004A compact fiber laser is demonstrated with use of a Gires-Tournois compensator and a short length (2-4 cm-long) of highly doped ytterbium (Yb) fiber providing net anomalous group-velocity dispersion. With use of a novel semiconductor saturable absorber mirror based on GaInNAs structure, self-started 1.5-ps-pulse mode-locked operation was obtained at ...

The graphene mode-locked fiber laser
SPIE Proceedings, 2011Starting from the structure of graphene, the electrical and optical properties of graphene is analyzed in this paper. Then, the transmission characteristics and the modulation for the optical pulses are discussed with the graphene waveguide model. Finally, the graphene based on the mode-locked fiber laser system is simulated, thereafter the role played

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.

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 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.

Bidirectional mode-locked thulium-doped fiber laser
Applied Optics, 2018We report a bidirectional mode-locked thulium-doped fiber laser. Mode-locking is enabled by the combination of semiconductor saturable absorption and nonlinear polarization rotation. Two stable mode-locked picosecond pulse trains in opposite directions are generated with a fundamental repetition rate of ∼16.57 MHz.

Actively mode-locked visible upconversion fiber laser
Optics Letters, 2000Active mode locking of a Pr(3+)/Yb (3+) -doped upconversion fluoride fiber laser with an all-fiber ZnO acousto-optic phase modulator is demonstrated for the first time to the authors' knowledge. Optical pulses of ~550-ps duration with a repetition rate of 239 MHz at a wavelength of 635 nm have been generated.

High-sensitivity mode-locked fiber laser gyroscope
Optics Letters, 1997We report significant performance improvement of a mode-locked fiber laser gyroscope. A Fabry-Perot cavity GaAlAs laser diode whose front facet was antireflection coated was used as a gain medium. The rms noise equivalent rotation rate measured with a time-interval counter was improved to 0.06deg/ radicalh.

Mode-locked Yb-doped Bragg fiber laser
Optics Letters, 2009We report on a mode-locked fiber laser featuring an Yb-doped large-mode-area Bragg fiber and exploiting dissipative-soliton pulse shaping. Reliable self-starting mode-locking is achieved using a fast semiconductor saturable absorber mirror. The laser generates 30 nJ chirped pulses at 17 MHz repetition rate for an average power of 510 mW.
