Passively synchronized Q-switched and mode-locked dual-band Tm3+:ZBLAN fiber lasers using a common graphene saturable absorber

Dual-band fiber lasers are emerging as a promising technology to penetrate new industrial and medical applications from their dual-band properties, in addition to providing compactness and environmental robustness from the waveguide structure. Here, we demonstrate the use of a common graphene saturable absorber and a single gain medium (Tm3+:ZBLAN fiber) to implement (1) a dual-band fiber ring ...

Sub-100 fs mode-locked erbium-doped fiber laser using a 45°-tilted fiber grating.

We demonstrate generation of sub-100 fs pulses at 1.5 µm in a mode-locked erbium-doped fiber laser using a 45°-tilted fiber grating element. The laser features a genuine all-fiber configuration. Based on the unique polarization properties of the 45°-tilted fiber grating, we managed to produce sub-100 fs laser pulses through proper dispersion management. To the best of our knowledge, this is the...

The Evolution of Dual-Wavelength Dissipative Soliton in Yb-Doped Fiber Lasers

Dual-wavelength dissipation soliton (DS) in the all-normal-dispersion ytterbium-doped fiber laser (YDFL) is reported. Using a phase-shift long period fiber grating (PS-LPFG) as an all-fiber format spectral filter in the laser cavity, self-starting dual-wavelength pulses are obtained by nonlinear polarization evolution (NPE). The mode-locking mechanism of the ANDi cavity with different central w...
