Abstract: Pulsed femtosecond (“ultrafast”) lasers are a trending tool with a vast variety of applications in science and engineering. The current trend towards more and more powerful pulsed lasers in the mid- and far-infrared spectral range enables application of established techniques, like multidimensional spectroscopy and quantum control approaches in these wavelength regimes. These efforts will produce new insights in dynamics of couplings on the atomic level and allow for a better understanding of reaction pathways of catalytic processes in material science or in the life sciences. This work presents the development of a source for light-phase ("CEP") stable femtosecond pulses in the mid-infrared spectral range. The wavelength of the pulses is tunable between 7 and 15 µm. The pulses are shaped in the time domain by deliberately delaying and/or attenuating frequency components in the spectral domain. The result is arbitrary control of the frequency distribution within these ultrashort pulses paving the way towards experiments of highly complex control over molecular vibrational excitations even in the electronic ground state.
