Summary: A 1.5 at.% Nd3+ and 0.5 at.% Ho3+ co-doped CeF3 single crystal was successfully grown and its absorption and fluorescence characteristics were evaluated. The spectroscopic properties of the crystal were investigated based on the Judd-Ofelt theory, and the fluorescence lifetimes of Nd3+ and Ho3+ were determined. Additionally, the magneto-optical performance of the crystal was studied for the first time, and the Verdet constants at different wavelengths were measured, showing its potential applications in lasers and magneto-optical devices.

Summary: The present study reveals the effects of neutron irradiation on the optical response of the Nd3+-doped Gd3Sc2Al3O12 (Nd:GSAG) single crystal in real-time and in-situ. The crystal showed transient and permanent transmittance reduction induced by neutron radiation, and the reduction mechanisms were analyzed. XRD characterization method confirmed the constant crystal structure before and after neutron irradiation. The generation of oxygen vacancies in the crystal caused a permanent reduction in transmittance after irradiation with neutrons.

Summary: A novel laser crystal Nd: CaGd0.1Y0.9AlO4 has been successfully grown by Czochralski method. The crystal with Gd3+ ions exhibits a more disorder structure compared to Nd: CaYAlO4 crystal. The crystal shows wider emission spectra and maintained wide absorption spectra. Through the as-grown crystal, dual-wavelength continuous-wave laser operation at 1358.4 nm and 1374 nm was achieved for the first time. These findings suggest that Nd: CaGd0.1Y0.9AlO4 crystal is a promising disordered laser host for longer wavelength solid laser operation.

Summary: Complex Zintl phases have led to the discovery of a new thermoelectric material Ca-9()(Zn1-xInx)(4)Sb-9 (x ~ 0.9), with a structure characterized by TSb4 tetrahedra and ZnSb3 triangular units forming [T4Sb9](18-) polyanions. The heavily-disordered structure exhibits semiconducting behavior, confirmed by single crystal electrical conductivity and Seebeck coefficient measurements which suggest degenerate p-type semiconductors.

Summary: In this paper, a laser diode array pumped transversely circulating inorganic lasing liquid based laser is demonstrated. The lasing liquid, consisting of 0.3 mol/l trivalent neodymium (Nd3+) ions, is synthesized using a mixture of phosphorous oxychloride (POCl3) and tin tetrachloride (SnCl4). The laser cell is side-pumped in close-coupling configuration by vertically arranged laser diode bars in an array. The lasing liquid is circulated transversely through the laser cell at flow rates of 10-12 l/min under laminar flow regime to replenish the heated lasing liquid. The results show the power scalability of liquid laser with increased optical-optical efficiency.

Summary: The crystal structures of CVO:Cr single crystals doped with over-stoichiometric 0.01, 0.05, and 0.1 wt% Cr2O3 grown by the Czochralski method were determined. The presence of chromium in multiple calcium sites and its coordination as octahedral Cr3+ and tetrahedral Cr4+ were revealed. The green or yellow color of CVO:Cr was found to be attributed to the valence state of chromium, Cr3+ or Cr4+. The structural behavior of transition metal ions with variable formal charge in CVO structure was summarized and analyzed.

Summary: Microvoids, well-known crystal defects, were observed for the first time in apparently scattering-free CeF(3) bulk single crystals, taking on the shape of perfect regular hexagonal-prisms. These microvoids are formed by the embedding of bubbles during the crystallization process, with sizes up to 13 mu m and heights in the submicron order.

Summary: This study compares and discusses the photoluminescence and X-ray radioluminescence of Ce:LaB3O6 (LBO) materials in both single crystalline and glassy forms, and finds that the host structure plays an important role in the luminescence properties of Ce3+. Crystalline Ce:LBO exhibits a narrow emission band with a small Stokes shift, while glassy Ce:LBO shows a broad emission band with a large Stokes shift. The presence of defects is also found to be higher in the glassy form. These results provide new insights into the contribution of the host structure to the luminescence properties of the dopant.

Summary: This study demonstrates that a post-growth thermal treatment is crucial for enhancing the light yield of Ce:Li6Y(BO3)(3) oxide. By reducing the concentration of intrinsic defects and scattering centers, the light yield is significantly improved by approximately 600%. Further optimization of the Ce3+ concentration and annealing time can potentially achieve a light yield comparable to state-of-the-art materials for thermal neutron detection.

Summary: Optical isolators (OIs) are necessary to protect laser sources from back-reflections. Single-crystalline Faraday rotators (FRs) with a large Verdet constant V, such as CeF3, are highly desired to reduce the cost and size of OIs. CeF3 has shown superior performance in terms of transmittance and figure-of-merit compared to the standard Tb3Ga5O12 (TGG), especially in the ultraviolet (UV) wavelength range.
