Philip Bucksbaum

Education: Harvard University A.B. 1975; University of California, Berkeley M.A. 1978; University of California, Berkeley Ph.D. 1980.

Professor Bucksbaum has several research projects in the Randall Laboratory, in the NSF Frontier Center for Optical Coherent and Ultrafast Science (FOCUS) at the University of Michigan, and in other laboratories in the United States and Europe. Most of these activities involve the study of atoms, electrons , and simple molecules in the presence of ultrahigh intensity coherent light. The light is produced by pulsed lasers, which generate amplified beams that can be focused to intensities exceeding an atomic unit, with pulse durations as short as 20 femtoseconds. The wavelengths extend from the far infrared to the extreme ultraviolet. In the infrared, this means durations of only one-half of a field cycle. The principal application of these intense fields is control of quantum systems. Professor Bucksbaum is en gaged in experiments that use "half-cycle" pulses to control quantum "wave packets" in molecules and atoms. His group has built computer controlled pulse shapers to study problems as diverse as chemical bonds and quantum chaos. Professor Bucksbaum also uses atomic physics to study fundamental symmetries in nature. Other experiments include the behavior of atoms in relativistic plasmas produced by terawatt laser beams, and the production of coherent vacuum ultraviolet radiation. Graduate students are involve d in Professor Bucksbaum's work at all levels, including building the lasers; designing, building, and performing the experiments; and doing calculations.

Professor Bucksbaum is a member of the National Academy of Sciences, a Fellow of the America Physical Society, and the Optical Society of America. He is Editor of VJUltrafast, the APS Virtual Journal of Ultrafast Science. He is also a recipient of the 2000 Margaret and Herman Sokol Faculty Award in the Sciences.
