Laser cooling in Yb:KY<sub>3</sub>F<sub>10</sub>: a comparison with Yb:YLF Open
Laser cooling by anti-Stokes fluorescence is a technology to realize all-solid-state optical cryocoolers. We grew Yb 3+ -doped KY 3 F 10 (Yb:KYF) crystals as novel laser cooling media and compare their cooling performance to Yb 3+ -doped L…
