DOI: 10.1016/j.optcom.2019.01.070
Abstract: Abstract We report a high-power 2 μ m higher-order-mode thulium fiber laser passively mode-locked with a semiconductor saturable absorber mirror (SESAM). Based on both spatial-mode discrimination through tuning the SESAM’s feedback and spatial-mode-dependent spectral selection… read more here.
