Abstract

Transparent laser ceramics are the attractive gain medium for solid-state lasers. However, they have not been applied to the fiber lasers due to the difficulty of forming green fibers by traditional methods. In this study, a novel route combined aqueous gelcasting with capillary glass tube was designed to prepare Yb:YAG transparent ceramic fiber with a diameter of 1.0 mm and 43.0 mm in length for the first time. The slurry with high solid loading and low viscosity was smartly inhaled into the capillary glass tube to conquer the difficulty of casting. The green fibers without cracks and deformation had highly dense microstructure. The in-line transmittance of highly doped 15.0 at.% Yb:YAG transparent ceramic disc prepared from the same preparation conditions of Yb:YAG ceramic fiber was 80.0 % at 1064 nm. This study provides a novel route to prepare transparent ceramic fiber differing from extrusion processing, promoting the development of fiber laser.

Abstract

The discovery of single structure Ce3+ doped garnet transparent ceramics (TCs) with a broad full width at half maximum (FWHM) is essential to realize a high CRI for high-power white light emitting diodes (LEDs) and laser diodes (LDs). In this work, by utilizing the ion substitution engineering strategy, pure phase Gd3Sc2Al3O12:Ce3+ (GSAG:Ce) TC with a broad FWHM of 132.4 nm and a high CRI value of 80.7 was fabricated through the vacuum sintering technique for the first time. The optimized in-line transmittance of TCs was 58.4% @ 800 nm. Notably, the GSAG:Ce TCs exhibited a remarkable red shift from 546 nm to 582 nm, with a high internal quantum efficiency (IQE) of 46.91%. The degraded thermal stability in Ce:GSAG TCs was observed compared with that of Ce:YAG TC, owing to the narrowed band gap of GSAG. Additionally, remote excitation white LEDs/LDs were constructed by combining GSAG:Ce TCs with blue LED chips or laser sources. A tunable color hue from yellow to shinning white was achieved in white LEDs, whereas the acquired CRI and CCT of the white LDs were 69.5 and 7766 K, respectively. This work provides a new perspective to develop TCs with high CRI for their real applications in high-power white LEDs/LDs.

Abstract

Previous studies demonstrated that live Mycobacterium leprae (M. leprae) infection promoted macrophage differentiation toward the M2 type, with elevated interleukin (IL)-10 production. The underlying mechanism is not entirely clear. In this study, we treated macrophages with primary M. leprae strains isolated from both lepromatous leprosy (L-lep) and tuberculoid leprosy (T-lep) patients. We found that infection by live M. leprae, regardless of the primary strain, resulted in M2 skewing in the infected macrophage. This skewing was associated with downregulated IRGM expression, a core organizer protein in the autophagy assembly and reduced autophagosome formation, and with lower annexin V staining and lower caspase 3 and caspase 9 activity. Moreover, live M. leprae-infected macrophages prevented efficient phagocytosis by uninfected bystander macrophages. As a result, the phagocytes secreted less pro-inflammatory cytokines, and preferentially primed anti-inflammatory T cell responses. Together, these results suggested that live M. leprae could employ a strain-independent mechanism to suppress inflammation, possibly involving the inhibition of autophagy and apoptosis in the infected macrophages.
