Femtosecond Bloch vector control in quantum wells

Jeremy J. Baumberg, Albert P. Heberle, Klaus Köhler

Summary form only given.We report on a general approach to coherent control in semiconductors, based on optical waveforms with synthesized intensity and phase versus time. This technique is limited only by the bandwidth of the initial laser pulses and the spectral resolution of the pulse-shaping apparatus. It is therefore especially suitable to investigate effects such as off-resonant Rabi oscillations and polaritons in multiple quantum wells. Experiments were performed in four-wave mixing (FWM) and differential reflection geometry based on a mode-locked Ti:sapphire laser emitting 100-fs pulses.

Influence of amplification on pulse shaping for coherent control applications

Anton du Plessis, GN Botha, LR Botha

We demonstrate here the importance of using low seed laser powers for amplification of shaped pulses in a typical setup for coherent control experiments. An acousto-optic programmable dispersive filter (Dazzler from FastLite) is used to shape 130 fs pulses before amplification. These devices hold many advantages as compared to other pulse shaping devices [1]. Pulse shaping must be done with care in this configuration, as will be demonstrated with a number of examples of measured pulse shapes before and after amplification.
