A high-order harmonic pump-probe setup using annular-beam interferometers

Abstract: Demands are specified for an interferometer setup capable of supporting attosecond resolution pump-probe experiments, as well as molecular alignment experiments. A design for two interferometers fulfilling these demands is presented. As the presented setup relies on annular beams for discrimination, high-order harmonic generation is attempted using annular beams. The success of these experiments as well as calculations performed indicate that this setup will function as intended.
