Extreme ultraviolet wave packet interferometry using tabletop high harmonic generation

Quantum interference techniques such as wave packet interferometry (WPI) in the extreme ultraviolet (XUV) regime set the basis for advanced nonlinear spectroscopy methods, such as multidimensional spectroscopy. These methods are however very difficult to implement at short wavelengths due to the required high phase stability and sensitivity. Recently, we have overcome these difficulties and have introduced a concept to implement such experiments with XUV free-electron lasers. In this project, we are developing a new setup optimized for seeding tabletop high-harmonic generation sources which is based on acousto-optic modulation of intense near infrared pulses. The project is a collaborative work between the groups Prof. F. Stienkemeier and Prof. G. Sansone.
