论文摘要
激光冷却利用光散射的物理学来冷却原子和分子气体，以接近绝对零。这是所有原子气体实验的关键初步步骤，其中bose-Einstein凝结并更普遍地达到了量子退化。激光冷却方法的持续发展使更多的元素被带到量子脱落性，每种其他原子物种都提供自己的实验机会。改进的方法正在开放新的途径，例如，纯粹是通过激光冷却以及连续的玻色 - 因斯坦凝结的实现，纯粹通过激光冷却到达了玻璃体的渠道。在这里，我们回顾了激光冷却中的这些最新创新，并提供了可能使新方法创造量子气的方法的前景。
Laser cooling exploits the physics of light scattering to cool atomic and molecular gases to close to absolute zero. It is the crucial initial step for essentially all atomic gas experiments in which Bose-Einstein condensation and, more generally, quantum degeneracy is reached. The ongoing development of laser-cooling methods has allowed more elements to be brought to quantum degeneracy, with each additional atomic species offering its own experimental opportunities. Improved methods are opening new avenues, for example, reaching Bose-Einstein condensation purely through laser cooling as well as the realization of continuous Bose-Einstein condensation. Here we review these recent innovations in laser cooling and provide an outlook on methods that may enable new ways of creating quantum gases.
