title: Single-frequency DBR lasing by integrating FBGs into germanium-free photosensitive highly Yb3+-doped silica fiber
title: Single-frequency DBR lasing by integrating FBGs into germanium-free photosensitive highly Yb3+-doped silica fiber

description: Monolithic distributed Bragg reflector (DBR) cavity which directly integrates fiber Bragg gratings (FBGs) into the photosensitive RE-doped fibers is a promising configuration in constructing compact and efficient single frequency fiber lasers (SFFLs). Yet, the doping level of rare-earth (RE) ions has generally to be sacrificed in the classical Ge-photosensitized RE-doped silica fibers because of the dramatic refractive index increase caused by the introduction of Ge. Here, we demonstrate an approach to realize the trade-off between photosensitivity and RE doping concentration. We validate that the addition of a small amount of cerium (0.37wt.%) instead of Ge could photosensitize Yb3+-doped silica fiber (YDF), while maintaining fiber numerical aperture (NA) at 0.12 under a high 2.5-wt.% Yb doping level. Based on the short monolithic DBR cavity constructed by this germanium-free photosensitive highly YDF, a 1064 nm fiber laser with a 48.6% slope efficiency and an over 200 mW power on two orthogonally polarized modes could be realized. Further stable and linear-polarized 1064 nm SFFL is also demonstrated in a designed monolithic polarization maintaining cavity with an output power of 119 mW and an efficiency of 26.4%. Our results provide an alternative way to develop photosensitive highly RE-doped fibers towards monolithic laser cavity application

title: Coating post-processing treatment for material extrusion 3D-printed Al2O3-based ceramic
title: Coating post-processing treatment for material extrusion 3D-printed Al2O3-based ceramic

description: Material extrusion three-dimensional (3D) printing is an additive manufacturing technique for printing 3D models of complex structures. Ceramic parts can be produced layer by layer by extruding viscoelastic slurries through precision nozzles. However, lamination inevitably occurs during the extrusion process, which reduces the surface precision of the ceramic parts. Therefore, we developed a coating material and corresponding coating process to improve the surface accuracy. The surface roughness (Ra) of ceramic parts decreased from 12.5-30μm to 3.2-6.3μm by coating post-processing treatment. Further, the coating was firmly bonded with the substrate and that the coating did not crack and fall off at 1500 ℃. Finally, the ceramic shell after coating was poured with metal liquid, and the metal castings with good surface accuracy were obtained. This study demonstrates the improved surface accuracy of ceramic parts prepared by extrusion 3D printing and expands the application range of extrusion 3D printing technology.
