Abstract:Multimode fiber-based saturable absorbers enable mode-locking in
lasers, generating ultrafast pulses and providing an exceptional
platform for investigating nonlinear phenomena. Previous analyses in
the continuous-wave (CW) limit showed that saturable absorption can be
obtained due to nonlinear interactions between transverse modes. We
find experimentally that saturable absorption can be achieved, thanks
to the interplay of single-mode fiber nonlinearity and the
wavelength-de… Show more
