Femtosecond laser pulse shaping is the key technology in quantum control. So far, we were able to demonstrate pulse shaping with sub-cycle 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].
Supercontinua exceeding one octave are a prerequisite to generate few-cycle light pulses in the temporal domain. Combining supercontinuum generation spanning from the ultraviolet to near-infrared spectral region with high-throughput prism based pulse shaping [3] opens up the possibility to temporally steer wavepacket dynamics on the sub-cycle timescale expanding the technique to a broader range of electronic systems.
We present the current status of our setup for ultra-broadband amplitude and phase shaping of femtosecond laser pulses characterized by transient grating frequency resolved optical gating.
