THz generation

Application note THz

The THz spectral region is increasingly interesting for many applications. One way to generate THz radiation is to use near-infrared lasers and transform the radiation into the THz region. Thus, the most straight-forward approach for average power scaling of the THz radiation would be to increase the average power of the driving laser source.

Plasma-based approaches [1], photo-conductive antennas (PCA, [2]), as well as optical rectification (OR, [3]) and other processes based on nonlinear crystals [4, 5] can all benefit from high repetition rate driving lasers. AFS offers suitable systems based on Ytterbium or Thulium and the required nonlinear post-compression addons to enable efficient THz generation with unprecedented average power.
