Abstract
MXene is a promising two‐dimensional (2D) material that is widely used in electro‐photonic devices due to its unique properties. In this contribution, V 2 CT x , a novel MXene, was employed as a saturable absorber (SA) for hybrid passively mode‐locked fiber lasers. An ultra‐stable and self‐starting mode‐locked laser system with low threshold can be achieved using V 2 CT x nanosheets and nonlinear polarization evolution (NPE). Signal to noise ratio increased 13 dB compared with using only NPE SA. A 72 fs pulse duration is easily achieved from this hybrid mode‐locked fiber laser system. To the best of our knowledge, this is the shortest pulse duration generated from the Yb‐doped mode‐locked fiber lasers using a hybrid or 2D SAs. This study proves that MXene V 2 CT x nanosheets can be developed as suitable SAs and served as potential advanced ultrafast photonic devices in the future.
