Article Abstract
A simple all-fiber widely tunable phosphosilicate Raman fiber laser (RFL) of high efficiency has been developed. The laser has more than 50 nm tuning range, and generates up to 3.2 W of output power with 72% maximum slope efficiency. The output power is almost constant in the range 1258-1303 nm. The width and the spectral power density of the RFL output spectrum can be controlled by the detuning of its cavity fiber Bragg gratings (FBGs) thus being optimized for efficient frequency doubling.

In this paper, we report the use of femtosecond radially polarized vortex laser with MHz repetition rate for direct writing of cladding waveguides (WGs) and realization of waveguide laser oscillations in ytterbium-doped calcium fluoride crystal. The negative refractive index modification in Yb:CaF crystal is fabricated by the homemade all-fiber laser amplifier. At 976 nm pump wavelength, these Yb:CaF WGs can achieve continuous-wave (CW) laser oscillation.

In this work, we demonstrate a continuous-wave (CW) single-frequency DFG in a ZnGeP (ZGP) crystal driven by all-fiber near-infrared (NIR) fiber lasers, for the first time to our knowledge. The all-fiber NIR laser sources consist of a 1.

Employing an electric arc discharge technology, we couple a multi-mode fiber (MMF) and a single-mode fiber (SMF), resulting in an MZI characterized by centimeter-scale arms. The varied sensitivity of fiber modes to curvature makes the high-order modes of the MMF more prone to leakage when subjected to bending, leading to alterations in the output interference fringe pattern of the MZI.

We propose a novel miniaturized optical attenuator based on the evanescent-field coupling between two nanofibers. Benefiting from a wavelength-dependent waveguiding property of the coupled structure, a tunable attenuation with maximum extinction ratio of ~ 20 dB is demonstrated with an ultrawide optical bandwidth up to 0.7 μm in experiment.
