标题： Production of Ultracold Molecules with Chirped Nanosecond Pulses: Evidence for Coherent Effects

摘要： 我们使用纳秒时间尺度上的频率啁啾光，通过光缔合过程在最低三重态中产生超冷的$^{87}$Rb$_{2}$分子。 与分子形成的量子模拟相比，我们得出结论，相干受激辐射起着重要作用，并主要负责正啁啾和负啁啾之间观察到的显著差异。 显示英文摘要

摘要： We use frequency-chirped light on the nanosecond time scale to produce ultracold $^{87}$Rb$_{2}$ molecules in the lowest triplet state via the process of photoassociation. Comparing to quantum simulations of the molecular formation, we conclude that coherent stimulated emission plays an important role and is primarily responsible for the significant difference observed between positive and negative chirps.
