Large Area Optical Frequency Detectors for Single-Shot Phase Readout
Felix Ritzkowsky, Matthew Yeung, Engjell Bebeti +9
Attosecond science has demonstrated that electrons can be controlled on the sub-cycle time scale of an optical wave, paving the way toward optical frequency electronics. Using cont…
Highly efficient narrowband terahertz generation driven by a two-spectral-line laser in PPLN
H. T. Olgun, W. Tian, G. Cirmi +7
We demonstrate record conversion efficiencies of up to 0.9 percent for narrowband (1 percent relative bandwidth) THz generation by strongly-cascaded difference frequency generation…
Ultrafast electron diffractometer with Terahertz-driven pulse compression
Dongfang Zhang, Tobias Kroh, Felix Ritzkowsky +6
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…
Cascaded Multi-cycle terahertz driven ultrafast electron acceleration and manipulation
Dongfang Zhang, Moein Fakhari, Huseyin Cankaya +3
Terahertz (THz)-based electron acceleration and manipulation has recently been shown to be feasible and to hold tremendous promise as a technology for the development of next-gener…
Segmented Terahertz Electron Accelerator and Manipulator (STEAM)
Dongfang Zhang, Arya Fallahi, Michael Hemmer +8
Acceleration and manipulation of ultrashort electron bunches are the basis behind electron and X-ray devices used for ultrafast, atomic-scale imaging and spectroscopy. Using laser-…
Operation regimes, gain dynamics and highly stable operation points of Ho:YLF regenerative amplifiers
Peter Kroetz, Axel Ruehl, Anne-Laure Calendron +6
We present a comprehensive study of laser pulse amplification with respect to operation regimes, gain dynamics, and highly stable operation points of Ho:YLF regenerative amplifiers…
Terahertz-driven, all-optical electron gun
W. Ronny Huang, Arya Fallahi, Xiaojun Wu +7
Ultrashort electron beams with narrow energy spread, high charge, and low jitter are essential for resolving phase transitions in metals, semiconductors, and molecular crystals. Th…
Effective Path Towards Relativistic Transients at Millimeter Wavelengths
Sergio Carbajo, Anne-Laure Calendron, Huseyin Cankaya +6
We refine the method towards extraction of sub-cycle transients in the 0.1-1 THz frequency (mm-wavelength) range from optical rectification in lithium niobate using tilted pulse fr…
Overcoming Bifurcation Instability in High-Repetition-Rate Ho:YLF Regenerative Amplifiers
Peter Kroetz, Axel Ruehl, Gourab Chatterjee +7
We demonstrate a Ho:YLF regenerative amplifier (RA) overcoming bifurcation instability and consequently achieving high extraction energies of 6.9 mJ at a repetition rate of 1 kHz w…
