Characterization of an ytterbium-doped double-clad fiber laser passively mode-locked by nonlinear polarization rotation
Résumé
The properties of an ytterbium-doped double-clad fiber laser, passively mode-locked by nonlinear polarization rotation are investigated in this work. Cartographies of mode-locking regime versus halfwave plates orientations are presented for several values of the total cavity dispersion and for different pump powers. Bistability between the continuous and
the mode-locking regimes is pointed out. The effect of the total group velocity dispersion is described with a master mode-locking equation
