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…
400 kHz repetition rate THz-TDS with 24 mW of average power driven by a compact industrial Yb-laser
Celia Millon, Sarah Houver, Clara J. Saraceno
We demonstrate a high average power terahertz time-domain (THZ-TDS) spectrometer based on optical rectification in the tilted-pulse front geometry in lithium niobate at room temper…
8.7-W average power, in-band pumped femtosecond Ho:CALGO laser at 2.1 um
Weichao Yao, Yicheng Wang, Sergei Tomilov +7
We report on an in-band pumped SESAM mode-locked Ho:CALGO bulk laser with a record-high average power of 8.7 W and an optical-to-optical efficiency of 38.2% at a central wavelength…
Temperature-independent non-linear terahertz transmission by liquid water
Célia Millon, Johannes Schmidt, Sashary Ramos +4
Liquid water is one of the most studied substances, yet many of its properties are difficult to rationalize. The uniqueness of water is rooted in the dynamic network of hydrogen-bo…
50-W average power Ho:YAG SESAM-modelocked thin-disk oscillator at 2.1 um
Sergei Tomilov, Yicheng Wang, Martin Hoffmann +4
Ultrafast laser systems operating with high-average power in the wavelength range from 1.9 um to 3 um are of interest for a wide range of applications for example in spectroscopy,…
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…
