“…Since these early studies, there has been continued interest and development in YAG:Yb lasers. [345] In 2012, the Yb:YAG single-crystal fiber was prepared by micropulling-down, and the continuous output power and slope efficiency reached 251 W and 53% at 1030 nm, respectively, which is a record. [346] The concept of fully crystalline double-clad waveguide devices for bulk solid-state lasers became practicable when focus shifted from conventional round cross-section clad/core structures to rectangular shapes-a planar waveguide or a channel waveguide.…”

An aluminate is a compound containing an oxyanion of aluminum. Many aluminates are found in nature. A large number of phosphors that are used in various applications, such as scintillation detectors, optical thermometry, longlasting phosphorescence, solid-state lighting, solid-state lasers, upconversion, bioimaging, and plasma display panels, are based on aluminate formulae. This review focuses on the synthesis and characteristics of such phosphors. The conventional as well as novel methods of synthesizing these phosphors are reviewed. The emphasis on commercially important aluminate phosphors is discussed.

“…The ceramic fiber diameter was about 20 μm and bend radius was 3 mm [ 15 , 16 , 17 ]. Recently, a novel route that combined aqueous gelcasting with a capillary glass tube was designed to prepare a Yb: YAG transparent ceramic fiber with a diameter of 1.0 mm and length of 43.0 mm for the first time [ 18 ].…”

YAG ceramic fiber, with its high thermal conductivity and easy to achieve limit size, provides design flexibility as a laser gain medium. Its mainstream forming method was mainly high-pressure extrusion, but there were disadvantages, such as lack of flexibility. In this work, the flexible green body of YAG ceramic fiber was prepared by melt spinning. The melting characteristics of TPU with four different Shore hardnesses were systematically investigated. The microstructure, element homogeneity of the surface and fracture SEM images of the prepared ceramic fiber were also analyzed in detail. The optimized process parameters of YAG ceramic fiber preparation were as follows: the melting temperature was 220 °C, the screw feed rate of the double-cone screw extruder was F = 15.0 mm/min and the TPU-95A# was used. The ceramic fiber with the mass ratio of TPU-95A# to ceramic powder = 4:6 had the best microstructure quality. It had good flexibility and could be knotted with a bending radius of about 2.5 mm, and the tensile strength reached approximately 20 MPa. These results are crucial for advancing YAG ceramic fiber applications.
