A vibration-free, optical cooling refrigerator may imply revolutionary applications in different fields, therefore it is vital to explore new materials suitable for laser cooling below the cryogenic temperature. Here we demonstrate that the Yb 3+ -doped LuLiF 4 crystal is a promising material that could reach the cryogenic temperature limit (123 K) or even lower. With the doping concentration of 7.5%, the Yb 3+ -doped LuLiF 4 crystal can be optically cooled down from the room temperature to 141.8 K in a double-pass setup. Provided with better purity and multiple-pass of laser cooling in the crystal, the temperature limit can even reach as low as 89 K for the 7.5% Yb 3+ -doped LuLiF 4 crystal, thus making it a competitive candidate for laser cooling below the cryogenic temperature. • Optical cooling of the 7.5% Yb: LLF crystal to 141.8 K was demonstrated. • The optimum pumping wavelength of the Yb: LLF crystal for laser cooling was fixed. • The Yb: LLF crystal can be optically cooled down to cryogenic temperature.
