On the Brittleness of Maximum Likelihood Estimation for Gaussian Process Hyperparameter Optimization
Tyler R. Johnson, Kian Ben-Jacob, Christopher P. Muller +1
Machine learning (ML) has become an indispensable part of modern engineering design workflows. A crucial step in training an ML model is the selection of the loss function which ca…
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…
Ytterbium-laser-driven THz generation in thin lithium niobate at 1.9 kW average power in a passive enhancement cavity
Edoardo Suerra, Francesco Canella, Dario Giannotti +8
Single-cycle, high-power, high-repetition-rate THz pulse sources are becoming the cornerstone of several scientific and industrial applications. A promising and versatile method fo…
High-power single-cycle THz emission from large-area photoconductive emitters at 400 kHz
Mohsen Khalili, Yicheng Wang, Stephan Winnerl +1
We report high average power THz emission from a GaAs-based large-area photoconductive emitter, excited by a commercial Yb-laser amplifier without any compression schemes, doubled…
