High quality laser systems make possible the control and investigation of atoms and molecules with exquisite precision. This Major Research Instrumentation (MRI) award supports the acquisition of a broadly tunable laser system which will open up large swathes of the periodic table for study. Combining the light with different elements, the PIs will conduct experiments ranging from searching for new force carrying bosons, to studying nuclear structure, and investigating molecular collisions. The instrument will enrich laboratory instruction, as undergraduate student researchers at Bucknell University and Susquehanna University will gain first-hand experience working with state-of-the art instrumentation in atomic and molecular physics.A continuous wave (CW) frequency quadrupled titanium sapphire laser covering significant sections of the 250 to 1000 nm spectral window will be acquired and integrated into the atomic, molecular and optical (AMO) physics lab at Bucknell University. The laser system will be used for experiments in precision isotope shift measurements motivated by searches of physics beyond the standard model, as well as molecular spectroscopy of alkali diatomic molecules with the aim of characterizing interaction strengths, collisions rates, and electronic potential energy curves. Undergraduate students from both institutions will be involved in all aspects of the experiments, gaining experience in atom, ion, and molecular spectroscopy, laser cooling, ion trapping and other skills which are central to contemporary work in AMO physics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

高质量的激光系统使精确控制和研究原子和分子成为可能。这一重大研究仪器(MRI)奖支持购买一种可广泛调谐的激光系统，这将打开大片元素周期表供研究之用。将光与不同的元素相结合，PI将进行一系列实验，从寻找新的携带玻色子的力，到研究核结构，以及调查分子碰撞。该仪器将丰富实验室教学，因为巴克内尔大学和萨斯奎汉纳大学的本科生研究人员将获得使用最先进的原子和分子物理仪器的第一手经验。覆盖250到1000 nm光谱窗口的重要部分的连续波(CW)频率四倍频钛蓝宝石激光器将被获取并集成到巴克内尔大学的原子、分子和光学(AMO)物理实验室。激光系统将用于精密同位素位移测量的实验，这些实验是由标准模型以外的物理搜索推动的，以及碱性双原子分子的分子光谱，目的是表征相互作用强度、碰撞率和电子势能曲线。来自两所大学的本科生将参与实验的所有方面，获得原子、离子和分子光谱学、激光冷却、离子捕获和其他技能方面的经验，这些技能是当代AMO物理工作的核心。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
