Effects of the carrier-envelope phase of few-cycle laser pulses on atomic bound states — •Fabian Elster1,2, Anne Harth1,2, Stefan Rausch1,2, Thomas Binhammer1,2, Mathias Hoffmann1,2, and Uwe Morgner1,2 — 1Institut für Quantenoptik, Leibniz Universität Hannover, Hannover, Germany — 2Quest: Center for Quantum Engineering and Space-Time Research, Hannover, Germany
We present a setup to study effects of the carrier envelope phase (CEP) of a sub-5-fs pulse from a phase stabilized Ti:sapphire laser oscillator with pulse energies in the nJ regime by spectroscopic observation of the excited atomic gas target to obtain the population of an atomic bound state. Theoretical work indicates a small dependence of the population on the CEP of the exciting pulse. We analyze the qualification of different atomic systems (alkaline and alkaline earths) with respect to the expected overall signal strength with a comprehensive theoretical model. On this basis, we discuss the details of the experimental setup.
