We report the Stark deceleration of CaF molecules in the strong-field seeking ground state and in a weak-field seeking component of a rotationally-excited state. We use two types of decelerator, a conventional Stark decelerator for the weak-field seekers and an alternating gradient decelerator for the strong-field seekers, and we compare their relative merits. We also consider the application of laser cooling to increase the phase-space density of decelerated molecules.
我们报告了 CaF 分子在强场搜索基态和弱场搜索旋转激发态分量中的 Stark 减速现象。我们使用了两种类型的减速装置,一种是用于弱场搜索者的传统 Stark 减速装置,另一种是用于强场搜索者的交变梯度减速装置,并比较了它们的优缺点。我们还考虑了应用激光冷却来增加减速分子的相空间密度。
