Series Of Experiments

Purpose of research. Testing a method for additive formation of low-melting materials through the use of a low-power solid-state (ytterbium) laser (maximum power 50 W). A series of experiments have been carried. As a result of those experiments, the elements of shaping mode have been obtained. They ensure the shaping of products without complete melting of the construction material while preserving the shape of a rough workpiece. Thus, the possibility of using this type of equipment for shaping products from low-melting materials in an additive way has been confirmed, which is the basis for further research on other materials, as well as the additional use of a shielding atmosphere. Methods. Methods of experiment planning and empirical data processing have been used for conducting experiments. Results. The possibility of using a low-power laser for the set tasks has been confirmed. Values ranges of shaping modes have been obtained, which ensure the formation of products made of low-melting materials by the partial melting technique through an additive method. Conclusion. The experimental studies have shown that a low-power solid-state laser can be applied for shaping products made of low-melting materials using an additive method. Applying the results of this study will allow further development of additive shaping of other metals (such as copper or aluminum), for which it is necessary to upgrade the equipment in terms of creating a shielding atmosphere in the melt zone, as well as increasing the laser power.

Fluoride crystals, due to their low phonon energies, are attractive hosts of trivalent lanthanide ions for applications in upconverting phosphors, quantum information science, and solid-state laser refrigeration. In this article, we report the rapid, low-cost hydrothermal synthesis of potassium lutetium fluoride (KLF) microcrystals for applications in solid-state laser refrigeration. Four crystalline phases were synthesized, namely orthorhombic K<sub>2</sub>LuF<sub>5</sub> (Pnma), trigonal KLuF<sub>4</sub> (P3<sub>1</sub>21), orthorhombic KLu<sub>2</sub>F<sub>7</sub> (Pna2<sub>1</sub>), and cubic KLu<sub>3</sub>F<sub>10</sub> (Fm3m), with each phase exhibiting unique microcrystalline morphologies. Luminescence spectra and emission lifetimes of the four crystalline phases were characterized based on the point-group symmetry of trivalent cations. Laser refrigeration was measured by observing both the optomechanical eigenfrequencies of microcrystals on cantilevers in vacuum, and also the Brownian dynamics of optically trapped microcrystals in water. Among all four crystalline phases, the most significant cooling was observed for 10%Yb:KLuF<sub>4</sub> with cooling of 8.6 $\pm$ 2.1 K below room temperature. Reduced heating was observed with 10%Yb:K<sub>2</sub>LuF<sub>5</sub>
