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…
High peak-power 2.1-μm femtosecond Holmium amplifier at 100 kHz
Anna Suzuki, Boldizsar Kassai, Yicheng Wang +5
High-power ultrafast laser sources in the short-wave infrared region are of great interest for numerous applications, including secondary sources of radiation and processing of mat…
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…
High-Dynamic Range Broadband Terahertz Time-Domain Spectrometer Based on Organic Crystal MNA
Samira Mansourzadeh, Tim Vogel, Alan Omar +7
We present a high power and broadband THz-TDS setup utilizing the nonlinear organic crystal MNA both as emitter and detector. The THz source is based on optical rectification of ne…
