自二十年前首次展示净冷却以来，固体的光学制冷已经发展到优于所有其他固态冷却过程。它已成为第一个也是唯一一个能够达到低温的固态制冷机，现在又是第一个在100 K以下进行固态制冷。这种实质性的进展需要一个多学科的方法，泵浦激光吸收增强，材料表征和纯化，热管理。在这里，我们提出了二十年的进展的高潮，从室温冷却到1091 K的记录。
Since the first demonstration of net cooling twenty years ago, optical refrigeration of solids has progressed to outperform all other solid-state cooling processes. It has become the first and only solid-state refrigerator capable of reaching cryogenic temperatures, and now the first solid-state cooling below 100 K. Such substantial progress required a multi-disciplinary approach of pump laser absorption enhancement, material characterization and purification, and thermal management. Here we present the culmination of two decades of progress, the record cooling to ≈ 91 K from room temperature.
