Optical generation of terahertz radiation is needed for many applications, but gaining high efficiency is still a challenge. The authors report a method to overcome dispersion effects in interfering chirp pulses used for THz pulse production by tunin

Terahertz- (THz-) based electron manipulation has recently been shown to hold tremendous promise as a technology for manipulating and driving the next generation of compact ultrafast electron sources. Here, we demonstrate an ultrafast electron diffra

Despite the popularity and ubiquity of the tilted-pulse-front technique for single-cycle terahertz (THz) pulse generation, there is a deficit of experimental studies comprehensively mapping out the dependence of the performance on key setup parameter

We present a compact ultrafast source tunable from 2 µm to 3.5 µm with 60 nJ pulses at 50 kHz repetition rate producing wideband spectra by adiabatic difference frequency generation supporting close to single-cycle pulses.

We map out the impact of the interaction lengths on the efficiency and terahertz spatial profile in tilted-pulse-front setups via systematically scanning the 5D-parameter space spanned by fluence, pulse-front tilt, crystal-position, and beam size.

We experimentally measure percent-level optical-to-multi-cycle terahertz conversion efficiencies by injecting a home-made wavelength- and duration-tunable two-line laser into periodically poled lithium niobate. We study the efficiency vs. the input l

Large-aperture, manually-poled LiNbO 3 wafers have already been used to generate THz radiation. However, the results were limited to room-temperature operation with only a few cycles. Here, we extend the number of cycles and improve the efficiency by
