This three-year award will support the continuation of a U.S.-France cooperative research project in atomic, molecular and optical physics between Thomas Gallagher of the University of Virginia and Pierre Pillet of the Aime Cotton Laboratory in Orsay, France. The objective of their research is to investigate laser cooling and its application to collisional studies of relatively dense samples of cold Rydberg atoms. They will study far infrared superadiant masers and multibody collisional energy transfer. The proposed experiments will be done with alkali atoms in laser cooled beams and in magneto-optical traps. The U.S. investigator brings to this collaboration his expertise on collisions of Rydberg atoms. This is complemented by the French investigator's expertise in laser cooling techniques and superadiance. The project will advance our understanding of the effects of Rydberg atoms in light scattering and collective light emission processes. This may eventually impact on the fabrication of diode lasers.

这一为期三年的奖项将支持美国继续-法国原子、分子和光学物理学合作研究项目，由弗吉尼亚大学的托马斯加拉格尔和法国奥赛艾梅科顿实验室的皮埃尔皮莱共同完成。 他们的研究目标是研究激光冷却及其在相对致密的冷里德伯原子样品碰撞研究中的应用。 他们将研究远红外超辐射脉泽和多体碰撞能量转移。所提出的实验将在激光冷却束和磁光阱中用碱原子进行。 这位美国研究人员为这次合作带来了他在里德伯原子碰撞方面的专业知识。 法国研究人员在激光冷却技术和超辐射方面的专业知识对此进行了补充。 该项目将推进我们对里德堡原子在光散射和集体发光过程中的作用的理解。 这可能最终影响二极管激光器的制造。
