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 near infra-red laser pulses at a central wavelength of 1036 nm from a co

We report on a laser system delivering sub-100-fs pulses at 2.1-{\mu}m wavelength with an unprecedented combination of high peak power and high repetition rate. The amplifier system consists of a mode-locked oscillator seeding a regenerative amplifie

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 to the green. The LAE is pumped at 11.4 W of green average power (515

A novel balanced air-biased coherent detection scheme for capturing ultrabroadband terahertz (THz) waveforms is implemented. The balanced detection scheme allows for coherent detection at the full repetition rate of the laser system without requiring

We provide a comprehensive technical analysis of the data acquisition process with oscillating delay lines for Terahertz-time domain spectroscopy. The utilization of these rapid stages, particularly in high-repetition-rate systems, is known to enable

In the statistical literature, as well as in artificial intelligence and machine learning, measures of discrepancy between two probability distributions are largely used to develop measures of goodness-of-fit. We concentrate on quadratic distances, w

We present, to the best of our knowledge, the highest average power from a laser-driven single-cycle THz source demonstrated so far, using optical rectification in the titled pulse-front geometry in cryogenically cooled lithium niobate, pumped by a c

Emitters based on photoconductive materials excited by ultrafast lasers are well established and popular devices for THz generation. However, so far, these emitters, both photoconductive antennas and large area emitters, were mostly explored using dr

Excitations between localized 3d states of transition metal ions within crystalline solids, commonly known as d-d transitions, play a pivotal role in diverse phenomena across solid state physics, materials science, and chemistry. These transitions co

We introduce the QuadratiK package that incorporates innovative data analysis methodologies. The presented software, implemented in both R and Python, offers a comprehensive set of goodness-of-fit tests and clustering techniques using kernel-based qu
