This research program is developing the understanding of how strong field laser pulses can be used to control molecular dissociation and applying this understanding to characterizing non-equilibrium molecular wave functions. We are moving from demonstrations of control in atoms and simple molecules toward a quantitative understanding of molecular control and extending control to multi-electron systems. We aim to fuse wave function measurement with strong field laser control in order to see how the subtle features of molecular wave functions which we can characterize affect the chemically relevant dynamics (i.e. bond breaking and formation).This research program continually seeks to integrate teaching and research and impact a large range of participants. People involved in the research include undergraduate students (visiting students through the NSF Research Experience for Undergraduates program as well as students at Stony Brook University), local high school teachers (through the NSF Research Experience for Teachers program), graduate students, postdoctoral fellows and visiting scholars. Of the five PhD students in the group, three are women. The PI recently developed and taught a new graduate course closely coordinated with the research program, focusing on a time domain approach to atomic and molecular physics and coherent control. The group has developed close collaborations with two theory groups, emphasizing qualitative and quantitative interpretations of their measurements through detailed calculations and exposing the students in the group to both experiment and theory firsthand. The work is inherently multi-disciplinary, and encourages students to develop knowledge and interests at the boundary between physics and chemistry. It also provides excellent technical and scientific training in the enabling areas of optics, ultrafast laser technology, vacuum hardware, data acquisition hardware and computer programming.

该研究计划正在发展了解强场激光脉冲如何用于控制分子解离并应用这种理解以表征非平衡分子波函数的理解。我们正在从原子中的控制和简单分子的控制转变为对分子控制的定量理解，并将控制扩展到多电子系统。我们旨在将波浪功能测量与强场激光器控制融合在一起，以了解我们可以表征的分子波函数的微妙特征如何影响化学相关的动态（即键断裂和形成）。该研究计划不断寻求整合教学和研究并影响大量参与者。 参与研究的人包括本科生（通过NSF研究经验来拜访本科生的研究经验以及Stony Brook大学的学生），当地的高中教师（通过NSF研究经验的NSF研究经验），研究生，博士学位专家和访问学者。 在小组中的五个博士学位学生中，有三名是女性。 PI最近开发并教授了与研究计划紧密协调的新研究生课程，重点是用于原子和分子物理和相干控制的时域方法。 该小组已经与两个理论小组建立了密切的合作，通过详细的计算强调了对其测量的定性和定量解释，并将小组的学生展示了实验和理论。 这项工作本质上是多学科的，并鼓励学生在物理和化学之间的边界发展知识和兴趣。 它还在光学，超快激光技术，真空硬件，数据采集硬件和计算机编程的能力领域提供了出色的技术和科学培训。
