Amplitude, relative phase, and polarization characterization during ultrashort pulse of hybrid mode-locked thulium-doped all-fiber laser. [PDF]

Sci Rep
Applications of ultrashort pulses at 1.9  $${\upmu }$$ m, such as micromachining, nonlinear imaging, and harmonic generation, require knowledge of the amplitude, phase, and polarization during the pulse. Therefore, the aim of this work is to characterize

Pulse Dynamics of an All-Normal-Dispersion Ring Fiber Laser Under Four Different Pulse Regimes

IEEE Access, 2020
Based on the coupled Ginzburg-Landau equations and Jones matrices of the waveplates considered, a numerical model of an all-normal-dispersion fiber laser mode-locked by nonlinear polarization rotation has been proposed.
