Femtosecond laser pulse shaping is the key technology in quantum control. So far, we were able to demonstrate pulse shaping with subcycle temporal accuracy making use of phase and amplitude modulation of femtosecond laser pulses in the infrared spectral region [1]. The experimental demonstration of molecular strong-field control schemes was achieved [2].
Organic molecules typically show pronounced absorption bands lying in the ultraviolet (UV) spectral region. Tailoring ultrashort UV laser pulses with respect to temporal and spectral shape opens up the possibility to investigate electron dynamics within different organic molecules, e.g. chiral ones.
We present the current status of our 4f and acousto optical modulator based setup for amplitude and phase shaping in the ultraviolet.
