Multicycle Terahertz Generation Using High-Energy Pulse Trains
2023 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)
2023 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference, CLEO/Europe-EQEC, MunichMunich, Germany, 26 Jun 2023 - 30 Jun 20232023-06-262023-06-30

Frequency conversion in nonlinear crystals is a well-established method to provide narrowband, multicycle terahertz (THz) radiation for applications requiring high spectral purity like spectroscopy and electron acceleration [1], [2]. While significant progress has been made by using laser systems that produce pairs of narrow spectral lines separated by the THz frequency, optical-to- THz conversion efficiencies still remain below one percent [3], [4].

Low efficiencies for narrowband optical-to-terahertz down-conversion remain a primary limiting factor for many applications of intense, laser-driven terahertz (THz) sources, highly sought after in material science and THz acceleration. Although simulations predict improvements in efficiency by using tailored trains of laser pulses as a driver, few studies have targeted this configuration. [...]

[Piscataway, NJ] : IEEE 2 pp. () [10.1109/IRMMW-THz57677.2023.10298999]  GO
A main limitation for many applications of laser-driven sources of narrowband terahertz (THz) radiation in spectroscopy and particle acceleration is the low optical-to-THz conversion efficiency. Due to power limitations, it is often necessary to use small sizes of the optical pump beam in the range of the THz wavelength to achieve sufficient intensity to effectively drive the nonlinear process.

SPIE Photonics West LASE, San FranciscoSan Francisco, United States, 29 Jan 2024 - 31 Jan 20242024-01-292024-01-31
Proceedings of SPIE 12869, 128690M () [10.1117/12.3003195]  GO
Efficiencies of nonlinear optical-to-terahertz (THz) conversion below one percent remain a limiting factor for applications of multicycle THz radiation like THz-driven acceleration and inspired the use of multi-line pump spectra. To overcome the difficulty of phase stabilization of multiple narrowband sources required by the multi-line approach, we exploit its temporal analog, i.e., regular pulse trains with THz repetition rate, in which the THz waves generated by rectifying the individual pulses add coherently.

Gravitational signatures of ALP dark matter fragmentation
[DESY-24-024; arXiv:2402.10313]
European Physical Society Conference on High Energy Physics, EPS-HEP2023, HamburgHamburg, Germany, 21 Aug 2023 - 25 Aug 20232023-08-212023-08-25 Proceedings of Science / International School for Advanced Studies (EPS-HEP2023), 116 () [10.22323/1.449.0116]  GO
The misalignment mechanism for axion-like particles (ALPs) is a leading explanation for dark matter. In this work we investigate ALPs with non-periodic potentials, which allow for large misalignment of the field from the minimum and make it possible for ALPs to match the relic density of dark matter in a large part of the parameter space.
