Collinear generation of few-cycle UV and XUV laser pulses for studying electron dynamics in solids — •Elisabeth Bothschafter¹, Ulrich Graf¹, Eleftherios Goulielmakis¹, Ralph Ernstorfer^{1, 2}, Reinhard Kienberger^{1, 2}, and Ferenc Krausz^1,3 — ¹Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Strasse 1, D-85748 Garching, Germany. — ²Lehrstuhl für Experimentalphysik I (E11, Experimentalphysik), Technische Universität München, James Franck Strasse, D-85748 Garching, Germany. — ³Department für Physik, Ludwig-Maximilians-Universität, Am Coulombwall 1, D-85748 Garching, Germany.

The generation of isolated attosecond XUV pulses has been established in recent years [1]. More recently, the generation of few-cycle low-order harmonics has been demonstrated: sub-4 fs UV pulses are produced by third and fifth harmonic generation of few-cycle near-infrared (NIR) laser pulses in a gas target [2]. Now we investigate the possibility of the simultaneous generation of low-order harmonics and high-harmonic by two subsequent gas targets in a collinear geometry. Future experiments employing these unique light pulses for the study and control of electronic motion in nano-structured semiconductors will be discussed.
