Attosecond seeding of high energy rescattered electrons — •Kenneth Schafer — Department of Physics and Astronomy, Louisiana State University, Baton Rouge, LA 70803 USA
Twenty five years ago, advances in both theory and experiment transformed strong field physics from a collection of interesting phenomena -- notably above threshold ionization and high harmonic generation -- into one of the most vibrant and relevant subfields of physics today. In this talk I will discuss work over the past decade to use attosecond pulses, the primary outgrowth of recollision physics, to study strong field processes themselves. In particular, we study the production of high energy photoelectrons via strong field-driven recollision when the tunnel ionization step is replaced by an attosecond pulse train. This allows insight into the rescattering of electron wave packets formed both near the laser field maxima, the normal tunnel ionization condition, and also near the laser field minima, something that does not occur via tunnel ionization.
