This grant supported experimental research in fundamental atomic, molecular, and optical physics. The project spanned a 25-year period, from 5/1/92 - 3/31/17. Specifically, the work involved interactions between atoms which were laser cooled to extremely low temperatures, less that 1 mK above absolute zero. Early in the project, the focus of the research was on studying ultracold collisions which occurred naturally in laser traps. This evolved into controlling these collisions, eventually leading into coherent control of the collisions with frequency-chirped laser light. The emphasis then switched to the formation of ultracold molecules from ultracold atoms by a specific type of ultracold collision: photoassociation. This laser-induced molecule formation was done with frequency-chirped light, maintaining the theme of coherent control on nanosecond time scales. The support from the grant was used to pay salaries of the PI, postdocs, and graduate students; for travel to professional meetings; and to purchase the equipment and supplies necessary to carry out the experiments. Results of the research were reported at conferences and published in peer-reviewed journals.
