As diode pumped solid-state lasers become more powerful, improved thermal management techniques are required. Minimizing thermal gradients in the laser increases performance and reduces thermal stress, which can cause failure by fracturing. Two-phase sprays provide an isothermal cooling method capable of dissipating high heat fluxes produced by the laser. A three-dimensional model of a spray-cooled, end-pumped solid-state laser has been developed to examine the temperature distribution within the laser slab. The model includes variable multi-nozzle arrangements, spatial distribution of two-phase heat transfer coefficients within each spray pattern, and non-uniform heat generation. A study has been conducted to minimize the range of surface temperatures across the slab by varying nozzle spacing. Two-dimensional temperature profiles at the sprayed surface and at the slab mid-plane have been generated. Results indicate that two-phase spray cooling can remove large heat fluxes and maintain temperature variations within acceptable limits. A new technique for designing and analyzing two-phase thermal management systems for solid-state lasers has been developed.

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>
