Coherent strong field spectroscopy: towards zeptosecond physics

Through the process of high-harmonic generation we study the atomic and molecular structure. This inherently-coherent process allows for the complete measurement of the photoionization dipole (magnitude and phase). Our experiments provide, angle, energy and time dependent information of multiple orbitals in molecular systems. The experiments make use of a newly developed attosecond interferometer that provides a resolution of 12.7 attoseconds with a precision as good as 680 zeptoseconds. I discuss further applications of the interferometer for attosecond pulse control and measurement. Similar techniques can be applied to nano-scale objects as well as solids. Finally, I’ll mention some of our new optics developments that lay a path for waveform synthesis in the optical regime and take strong field physics to the semiclassical regime.

Coffee will be served prior to the talk, at 3:00 p.m., In Room P-121
