Appl. Phys. B 126, 2 (2020) We present on THz generation in the two-color gas plasma scheme driven by a
high-power, ultrafast fiber laser system. The applied scheme is a promising
approach for scaling the THz average power but it has been limited so far by
the driving lasers to repetition rates up to 1 kHz. Here, we demonstrate recent
results of THz generation operating at a two orders of magnitude higher
repetition rate. This results in a unprecedented THz average power of 50 mW.
The development of compact, table-top THz sources with high repetition rate and
high field strength is crucial for studying nonlinear responses of materials,
particle acceleration or faster data acquisition in imaging and spectroscopy.
