One of the most perspective methods of additive manufacturing is selective laser melting. It
allows producing the parts directly from 3D-model to 3D-object from metallic powders and …

Generation of high-order modes with high quality is important for the application of
cylindrical vector beams in fibers. We experimentally demonstrated high-order LP_11 mode …

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 …

Temporal and spatial resonant modes are always possessed in physical systems with
energy oscillation. In ultrafast fiber lasers, enormous progress has been made toward …

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 …

A wavelength-tunable LP 11 mode Q-switched Yb-doped fiber laser was demonstrated
based on black phosphorus. To the best of our knowledge, it's the first time to achieve …

A switchable multi-wavelength pulse fiber laser based on dual-Sagnac comb filter, nonlinear
optical loop mirror (NOLM) and a homemade mode selective coupler (MSC) is proposed …

A high-order-mode (HOM) Brillouin random fiber laser (BRFL) based on distributed Rayleigh
scattering in an all-few-mode fiber random cavity is proposed and experimentally …

We propose and demonstrate a mode and wavelength-switchable pulsed fiber laser using
two-mode fiber Bragg grating (TM-FBG) as both transverse mode converter and wavelength …

We propose mode couplers and converters based on dual-core hollow-core photonic
bandgap fiber (HC-PBGF) structures, which might be potential solutions for integrated all …
