Ultracold polar molecular gases promise new directions and exciting applications in collisions and chemical reactions at ultralow energies, precision measurements, novel quantum phase transitions, and quantum information science. Here we briefly discuss key experimental requirements for observing strong dipole-dipole interactions in an ultracold dipolar gas of molecules. We then survey current experimental progress in the field with a focus on our recent work creating a near quantum degenerate gas of KRb polar molecules [Ni et al., Science, 2008, 322, 231].
超冷极性分子气体有望在超低能碰撞和化学反应、精密测量、新型量子相变以及量子信息科学等领域开辟新的方向并带来激动人心的应用。在这里，我们简要讨论了在超冷偶极分子气体中观察强偶极力的关键实验要求。然后，我们综述了该领域的当前实验进展，重点介绍了我们最近在创造近量子简并的 KRb 极性分子气体方面的工作[Ni 等人，Science，2008，322，231]。
