Average-power scalability of multi-cycle terahertz sources based on periodically poled lithium niobate stacks
Patrick J. Dalton, Robin Löscher, Tim Vogel +6
We demonstrate that narrowband multi-cycle terahertz (MC-THz) sources based on periodically-poled lithium niobate (PPLN) wafer stacks can be driven by high repetition-rate, high en…

Laser-driven few-cycle Terahertz sources with high average power
Robin Löscher, Tim Vogel, Samira Mansourzadeh +5
Ultrafast laser-driven terahertz sources are gaining in popularity in an increasingly wide range of scientific and technological applications. However, many fields continue to be s…

Time-Resolved Measurements of Cumulative Effects in Gas Dynamics Induced by High-Repetition-Rate Femtosecond Laser Filamentation
Robin Löscher, Malte C. Schroeder, Alan Omar +1
The advent of high-average-power, ultrafast ytterbium-based lasers allows us to generate laser filaments at repetition rates ranging from 10s of kHz up to 100s of kHz. At such high…
