Extreme Nonlinear Optics in Semiconductors with Shaped Laser Pulses — •Matthias Reichelt¹, Andrea Walther², and Torsten Meier¹ — ¹Department of Physics and CeOPP, University of Paderborn, Warburger Str. 100, D-33098 Paderborn, Germany — ²Institut für Mathematik, Universität Paderborn, Warburger Str. 100, D-33098 Paderborn, Germany

If a two-level system is excited with an intense light field of several times the Rabi frequency, the well-known Mollow triplets appear in the emitted radiation spectrum. [1] We show that the pattern of the emission spectrum can be changed by using appropriately shaped [2] laser pulses. The effect is also observable for a more realistic description of a semiconductor system [3].
