Here, we investigated the nonlinear optical (NLO) characteristics of carboxyl-functionalized
graphene oxide (GO-COOH) in the near-infrared (NIR) region. The results revealed that GO …

We present a kind of harmonic mode locking of bound-state solitons in a fiber laser based
on molybdenum disulfide (MoS_2) saturable absorber (SA). The mode locker is fabricated …

We experimentally demonstrate a harmonically mode-locked Er-doped fiber laser. The
distinctive feature of the laser is highly stable pulse trains generated via self-starting hybrid …

Harmonically mode-locked soliton fiber lasers have been intensively investigated in recent
years due to their wide range of applications. Drawback of these lasers is relatively large …

Ultrafast lasers with tunable parameters in wavelength and time domains are the choice of
light source for various applications such as spectroscopy and communication. Here, we …

As a two-dimensional material, MXene has accordion-like structures and possesses highly
tunable and tailorable electro-optical capabilities, which suggests that it can be extensively …

Graphene, whose absorbance is approximately independent of wavelength, allows
broadband light–matter interactions with ultrafast responses. The interband optical …
