Cylindrical vector beams and vortex beams, two types of typical singular optical beams
characterized by axially symmetric polarization and helical phase front, possess the unique …

We provide a perspective overview of the emerging field of nonlinear optics in multimode
optical fibers. These fibers enable new methods for the ultrafast light-activated control of …

We report, for the first time to the best of our knowledge, the switchable generation of
versatile femtosecond and picosecond spatiotemporal mode-locked (STML) pulses in an all …

Spatiotemporal mode-locked (STML) fiber lasers attract great interest owing to their
distinctive spatiotemporal characteristics and potential to generate high-energy pulse …

We experimentally demonstrate two kinds of all few-mode fiber (FMF) ring lasers with high-
order mode (HOM) oscillation in the laser cavity. One kind is a switchable-wavelength all …

We investigate the focusing properties of cylindrical vector beams (CVBs) generated from
the combination of an array of beams, each with sub-apertures and controllable polarization …

The performances of mode-locked fiber lasers rest with the design and configuration of the
cavity, and their temporal morphologies are rarely linked with the modulation of transverse …

We propose and experimentally demonstrate an intra-cavity transverse mode-switchable
fiber laser based on a mode-selective photonic lantern and a few-mode Er-doped fiber …

We experimentally demonstrate a multi-wavelength fiber laser based on dual-Sagnac comb
filter with LP_11 modes output. The filter is used to generate comb spectrum, which is …
