The Field-Resolved Infrared Metrology Research Group has established a new collaboration between the Max-Planck-Institute of Quantum Optics and the University of British Columbia (UBC). In the frame of a postdoctoral fellowship within the Max-Planck-UBC-UTokyo Center for Quantum Materials, group member Dr. Maximilian Högner joins forces with partners at the UBC to further investigate a novel, power-scalable platform for cavity solitons recently discovered at the MPQ [1].
The technology will serve as a source of energetic, self-stabilizing, few-cycle visible and near-infrared pulses at multi-MHz repetition rates and promises unprecedented pulse quality and noise characteristics, a desirable – yet very challenging – regime for coherent spectroscopy applications. Such sources will allow sensitive spectroscopic studies of 2D quantum materials, like the investigation of high-temperature Bose-Einstein condensates [2], and their extension to the mid-infrared range. In addition, they are likely to benefit cavity-enhanced high-order-harmonic generation [3].
