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…
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…
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…
Hybrid air-bulk multi-pass cell compressor for high pulse energies with full spatio-temporal characterization
Alan Omar, Martin Hoffmann, Geoffrey Galle +2
Multi-pass cell (MPC) compressors have proven to be the method of choice for compression of high average power long-pulse Yb lasers. Yet, generating sub-30 fs pulses at high pulse…
Towards Intense Ultra-Broadband High Repetition Rate Terahertz Sources Based on Organic Crystals [Invited]
Samira Mansourzadeh, Tim Vogel, Alan Omar +4
Increasing the average power of broadband, few-cycle terahertz (THz) sources is currently a topic of intense investigation, fueled by recent immense progress in high average power…
Spectral broadening of 2 mJ femtosecond pulses in a compact air-filled convex-concave multi-pass cell
Alan Omar, Tim Vogel, Martin Hoffmann +1
Multi-pass cell (MPC) based temporal pulse compressors have emerged in the last years as a powerful and versatile solution to the intrinsic issue of long pulses from Yb-based high-…
Broadband THz-TDS with 5.6 mW average power at 540 kHz using organic crystal BNA
Samira Mansourzadeh, Tim Vogel, Alan Omar +3
We demonstrate efficient optical rectification in the organic crystal BNA (N-benzyl-2-methyl-4-nitroaniline), driven by a temporally compressed, commercially available industrial Y…
Average power scaling of THz spintronic emitters in reflection geometry
Tim Vogel, Alan Omar, Samira Mansourzadeh +10
Metallic spintronic THz emitters have become well-established for offering ultra-broadband, gap-less THz emission in a variety of excitation regimes, in combination with reliable f…
