Performance Enhancement via XPM Suppression in a Linear all-PM NPE Mode-locked Fiber Oscillator
Abstract
We demonstrate strong performance enhancement of an all polarization-maintaining fiber oscillator mode-locked using NPE in a linear self-stabilized fiber interferometer via suppression of cross-phase modulation (XPM). Numerical simulations reveal that XPM significantly affects the saturable absorber dynamics resulting in distortions of mode-locked steady-states. In the experiment, we construct an oscillator with XPM suppression, employing an intra-cavity YVO4 crystal, and compare its characteristics with a reference oscillator in standard configuration. It is shown, that XPM suppression not only lowers the mode-locking threshold by more than 40%, but further results in improved spectral pulse quality at the output ports and reduced nonlinear loss of the artificial saturable absorber.
