摘　　要：超冷分子的理论和实验研究近年来取得了令人瞩目的巨大成就，极大地拓展了原子分子光物理的研究范畴。围绕超冷分子的制备与应用开创了很多全新的研究领域，如超高分辨分子光谱、分子量子态操控、精密测量以及量子模拟等。当前超冷分子的高效密集制备主要采用基于激光冷却的超冷原子缔合技术来实现。文章综述了超冷分子缔合制备的研究现状，阐述了光缔合、Feshbach共振缔合、受激拉曼绝热跃迁以及超短脉冲光缔合产生超冷分子的物理机制与实验进展，对外场操控超冷分子的实验结果及其潜在应用做了概要展示。Theoretical and experimental research on ultracold molecules in recent years has made remarkable achievements, and greatly extended the domain of atomic, molecular and optical physics. Various completely new fields such as high resolution molecular spectroscopy, quantum manipulation of molecular states, precision measurement and quantum simulation have been initiated, centered on the production and application of ultracold molecules. Currently, efficient creation of ultracold dense molecules is mainly realized based on the photoassociation of laser pre-cooled ultracold atoms. This article summarizes the status of the preparation of ultracold molecules by photoassociation, and reviews the physical mechanism and experimental production of ultracold molecules using photoassociation, Feshbach resonance, stimulated Raman adiabatic passage （STIRAP）, and ultrashort pulse photoassociation. To conclude, some experimental results and potential applications for the manipulation of ultracold molecules via external fields are presented.
